A guy has a few drinks at a bar, then heads to the rest room. While he’s doing his business, a very short man takes the urinal next to him and whips out a 10-inch johnson.

“I’m sorry for staring,” says the guy, “but you’re huge.”

“That’s because I’m a leprechaun,” says the short man. “All leprechauns are well-endowed.”

“I’d do anything to have a penis that size,” sighs the guy.

“It just so happens that I can grant wishes,” says the leprechaun. “If you let me have sex with you in the bathroom stall, I’ll give you a bigger penis.”

The man thinks it over and decides he wants a giant schlong. As they’re going at it, the man cries out, “I can’t believe I’m letting a leprechaun screw me!”

“I can’t believe that you believe I’m a leprechaun!”
