In the 3.5 days I was DMIng a campaign and we had a fighter/sorcerer who was building himself much the way a magus now is. He also spent skill points in performance: singing and profession:blacksmith. The party fAced a were-rat with pipes of the sewers and won, and said fighter decided to burn the pipes in a forge while he was working on his sword and singing. This was my first "you do what?" moment
I decided to play with the idea a bit as he was burning the musical magic item while working on his hereditary blade and introducing his own music, so when he learned to throw his sword to take out opponents, I said the whistling of the blade attracted rats and mice to the area. This was his "wait... What?!" moment.
He decided to burn this foul magic from the blade. Being a specialist in fire and lightning he prepped his spells, and then said "to burn the magic from the sword, I channel all my spells for the day thru it and plunge it into the ground."
I say "wait... What? Now? You know youre in the wild magic zone where arcane magic is unstable ,yes?"
Him "yup. I do it now."
So I let him burn the magic out. And then all the mice and rats in the forest became sentient and thought he was their creator god.
