Mustache Fairy

The Mustache Fairy leaves evidence of what the mustache bearer did the night before while drunk, within his or her mustache.

Mustached man: "I have no idea what I did last night, but apparently I drank a lot of beer."

Concerned friend: "I think you banged a chicken; the Mustache Fairy left a feather in your mustache."

Mustached man: "Yeah, and it stinks like beer and hot wings."
