A minotaur wanders into the tavern, takes a seat at the bar, orders a Guinness, and begins to complain to the bartender about the lousy night he's had.

"I just can't seem to get to sleep. And, when I do, I can't dream well because of my horns."

Gee, Bub, replies the bartender, "Sounds like you need to see a psychiatrist. Or maybe a veterinarian."

The minotaur finishes his Guinness and wanders back to his labyrinth.
