Two men in a sauna. The first one says to the second one, "Do you want to see a magic trick?"
Second guy says, "Sure."
"OK. Face away from me and get down on your hands and knees."
Second guy turns around and gets down on all fours.
"There," says the first one, "... does that feel like you've got a thumb up your ass?"
"Yes!"
The first guy waves both of his hands in the air, "Magic!"
