Coming from first edition, where all kinds of sparkly, magical treasures were lost by previous dungeon denizens while sitting on the commode, my players tend to exhibit a peculiar interest in such places. It'll take several messy, unfruitful search results, accompanied by failed Fort saves to contract filth fever to break them of it.
Seriously, any time a refuse pile, midden heap, outhouse, or other foul, noxious area appears in an adventure I run, these guys dive in head first.
