Leprechaun

There was this big football player in the bathroom taking a piss, when in walks this little short guy who stands beside him to piss.
The big guy couldn't help but notice the enormous size of the little guy's penis. He said to the little guy "I'm not gay or anything but how how in the hell can a guy so little have a dick so big?"
The little guy replied "Well I'm going to let you in on a little secret, I am a leprechaun. I can grant you any wish you want, but there is a catch, you have to let me stick this up your ass."
The big guy thought to himself "Well I have played football and got knocked on my ass, surely I can take the pain of a dick up my ass." He said "OK, my wish is for a million dollars."
The leprechaun said "bend over." and proceeded to have his way with the football player.
When it was over, the big guy exclaimed "I can't believe you got all that up in me."
The little guy said "I can't believe you thought I was a leprechaun!"
