Another one had a hijacked Faery Dragon as main topic.
I'm guessing you mean Euphoria Horrors from #34?
There was Old Man Katan... in issue 41, I think.
You think correctly.
Anyhoo, how about Song of the Fens, from Dungeon #40?
Of course, one easy recipe for a funny adventure is monster PCs, as demonstrated in Monsterquest (#10) and Rank Amateurs (#22).
Three more, marginally funny, adventures come to mind.
A Way With Words, from #41, has the PCs encounter...
Fraggart's Contraption, from #47, has the PCs study...
The Bandits of Bunglewood, from #51, has some NPCs tell frightful tales about horrible monster highwaymen, who turn out to be...

What the...? How on earth could I have forgotten the funniest one of all?!? I'm referring to A Question of Balance from #14. Just take one look at the picture on the first page of that adventure, and tell me it's not funny! Oh, the adventure itself might be deadly, and its consequences potentially serious (depending on how the DM chooses to run it.) But the premise! Oh, the premise!
The adventure begins with the PCs finding an angry mob, which is about to burn at the stake a demon from another world. The "demon" turns out to be...

Expanding the definition of "witty" to include "light tone" and "clever twists" or "mistaken identity" give a fairly long list of quality choices from older magazines (3rd Ed editors clearly shied away from comic fare) ...
Note that some duplication of previously-posted suggestions exists
032 – Changeling - Local shepherds are in terror since the recent arrival of a white dragon to the area. Find the lair of the beast and slay it before the shepherds join their flocks in the beast’s gullet. But beware, for “white” can indeed be misleading, especially when the name of the dragon is Whitefire.
032 - Pearlman's Curiosity - In this comic adventure, residents of the town of Grinley Crossing seem to have gone insane. Everything is upside-down, backwards or reversed. From the people to the animals no one is acting as they should ... usually the complete opposite. Investigate and put things right. Hint ... can you say “nilbog”?
034 – Euphoria Horrors - The cries of a distraught child ring through the woods as he searches for his lost play-companion “Drake”. The search for his missing friend leads to a tribe of tasloi who have become addicted to the Euphoria Gas breath-weapon of Drake, the faerie dragon.
036 - Troll Bridge - A Troll has recently taken residence beneath a small bridge, demanding that tolls be paid by any who would cross. But how vicious is that “troll” ... and did I really catch a glimpse of a gnome hiding nearby?
038 - Pandora's Apprentice - When the Mistress is away, the apprentice will play ... especially if she is a young genius able to sneak into the mage’s lab. Unfortunately, a flask of curses and the lure of magic items have become a bad combination for the young lady, who has taken to “liberating” magic items from adventurers.
038 – Things that Go Bump in the Night - Sylvan elves fear the recent haunting of hobgoblin ruins, but cannot investigate the taboo location. Really, the sounds are a firbolg demolition crew, but the giants have a request before they’ll stop work ... remove a powerful “witch” from their old home. But is this “dark witch” really evil, or just misunderstood.
040 - Song of the Fens - The lovely Martinique has been promised in marriage to a local knight. But her heart is given to the unknown singer whose enchanting voice rises above the stink of Vile’s Fen. She must seek the aid of adventurers to find her love, not realizing the beautiful voice is that of an outcast troll.
041 - Old Man Katan and Mushroom Band - Old Man Katan is a eccentric hermit who lives in the Glitchegumee swamp. He is accompanied (literally) by a patch of Camprestri ... singing mushrooms. Explore the swamp, meet its terrors, and see if you can survive Campestri Acapella. For those in need of comic relief, duh.
041 - Way With Words, A - A gnome scholar seeks brutish but historically inclined adventurers to recover a tome of Gnomish poetry he believes was stolen by a pretty bard. But the bard herself has been the victim of robbery, having been waylaid by a band of literate goblins who believe the tome of sappy love poems is a powerful spellbook.
045 – Rudwilla’s Stew - The Duke has a secret to keeping the Bugbear hordes from attacking. Every year he has the witch Rudwilla prepare a special stew as a “Birthday Tribute” for the chieftain. Now his birthday is only three days away, and the witch is short a few vital supplies, from hogroot to troll’s warts.
047 – Fraggart’s Contraption - When the gnome Fraggart was taken hostage his family quickly gathered and paid his ransom. But now he has sent a not claiming that he refuses to return home until he has finished with a recent “discovery”. A rescue is clearly in order.
048 – To Bite the Moon - Gnolls have been raiding the local traderoutes. Sneak into their cavern lair, but become the victims of an accidental “wish” that transforms the entire party into a band of gnolls themselves.
049 - Hair Today, Gone Tomorrow - Months after receiving a haircut from a dwarven barber, you suddenly find yourself magically teleported to his side and forced to protect him during a battle. This continues throughout the months, as you realize you’ve fallen victim to a diminutive sorcerer with a custom summoning spell.
049 – Lenny O’Brien’s Pot of Gold - A troublesome Leprechaun has stolen your valuables, and you are able to track him to a muddy pool. Can you get your items back ... and are you curious about why the river has been diverted and a rough aqueduct built, and why tracking the leprechaun was so simple?
051 - Bandits of Bunglewood, The - Terrible monsters, possibly even monstrous spirits, have begun raiding travelers upon the highway through the Bunglewood. Put an end to these attacks, but keep focused on finding the real culprits rather than get distracted by a band of mere kobolds slinking about the forest.
052 - Welcome to the Krypthome - Add together three dwarven miners, a missing fourth, a collapsed mineshaft, two moronic goblins, a Ring of Invisibility, a Bag of Tricks, and the workshop abode of a traveling mage who specializes in researching Wild Magic and what do you get ... Comic Relief !!!
054 - Witch's Fiddle, The - A band of Faerie musician has been attacked by a “witch” who stole the fiddle of one of the satyrs. Recover the instrument and bring the thief to justice, but remember that ever story has many sides and never judge a book by its cover.
057 – Carcas Fracas! - In the road before you lies the body of a hobgoblin, face down in the road. From the number of arrows sticking out of its back it is obviously dead ...
058 - Bad Batch of Brownies, A - Druid solo adventure - The Brownies of the Apple Wood are suddenly causing no end of havoc. A comic-relief adventure featuring well-intentioned brownies, a well of many worlds, and a recent visitor to the brownie’s grove who rides a “hog” with a “chick” on the back and hates the “lid” that the law makes him wear.
059 - Wedding Day - Two merchant families are about to be joined in marriage, and an ex-boyfriend is jealous. He is also rogue and former wizard’s apprentice, so trouble is to be expected. Comic relief adventure.
060 – Centaur of Attention - Trouble brews in a small village when a wizard passes through in a cart drawn by a vacuous centaur. Prevent a fight and mob lynching while settling the matter of the wizard and the centaur.
062 - Wild in the Streets - An evil wizard has released a horde of foul beasts to destroy the small, border town of Thenwick ... or perhaps the rare carnival animals of a traveling showman have escaped. Recapture the beasts without injuring them or destroying the town.
064 – Mad Chefs of Lac Anchois, The - Rescue Grippli before they become “frog’s legs” at the dinner table of Cloud Giant Chefs serving to a visiting delegation from the Cloud Giant Kingdoms.
068 – Artist’s Loving Touch, The - An elderly sculptor is using Gloves of Petrification and were-rat kidnappers to turn innocent victims into new masterpieces.
070 – Homunculus Stew - A mage’s homonculus is about to become dinner for an ogre. What the mage fails to mention is that he sent his tiny servant to steal spell components from the ogre’s cave.
076 - Day in the Market, A - A bumbling mage brings mayhem out of the sewers and into the market after a gray ooze eats his Wand of Wonder and begins “burping” magical effects.
080 – Frothing Miscreant - An inventive gnomish retired-adventurer with an inferiority complex has turned to piracy. Track down his lair and bring him to justice, but beware his “cruel inventions”.
088 – Make it Big - A band of hill giants threaten to crush a halfling village unless the heroes agree to a brief period of indentured servitude (to make the giants “nice things”). Only, the giants are so impressed with the quality of the heroes products, they decide to “extend” the contract.
089 - Wedding Bells - A wedding brings the PCs to the remote town of Dockalong, where a young halfling has mysteriously disappeared and a village outcast sulks in the woods. Can a glum satyr be convinced to give up his only “friend”, even if she is a half-fiendish harpy?
091 – Legend of Garthulga - Elven legends state that the undead Garthulga awakens every century to terrorize the countryside. Now appears to be its time, as some beast is terrorizing Barcus Thigwhistle’s Inn and Trading Post, driving off his business and eating his pet hog. Put an end to the attacks without running afoul of a trio of halvling “adventurers” who’s price to end the trouble is more than the now impoverished Barcus can afford.
109 – Devil Box, The - The kobolds have accidentally opened their “devil box” and released a very bitter kyton and three imps. They’ve hidden in a human town until they grow back to normal size (1 week), and the only kobold who can recapture them (a grotesquely fat moron) has been sold by the tribe to a Freak Show as the “reptile boy”.
126 – Menagerie, The - Monsters are running loose at “Gwen’s Relic’s”. A scaled-down “Asflag’s Unintentional Emporium” .
HTH,
Rez

I am looking for a witty or funny adventure in older Dungeon magazines. Does anyone remember one?
As an example there was a "wedding" adventure in the Dungeon magazine, where the PCs had to organize a wedding ceremony.
Another one had a hijacked Faery Dragon as main topic.
A bit late, but: I remember one called Rank Amateurs, from #22 I think, where the PCs play humanoid diplomats. It was pretty funny if I remember it right.
