The Leprechaun

A man walks into the bathroom, and steps up to a urinal. He can't help but notice the short man at the urinal next to him, and the large penis this man has.

He says to the short man:

- Excuse me, I couldn't help but notice what a large penis you have.

The short man replies:

- I am a leprechaun, and I can grant you three wishes.

The man is kind of skeptical, but he decides to believe him anyway.

- OK - He says - I want to live in a mansion.

The short man replies:

- Sure. Tomorrow morning you will wake up in it.

The man says:

- Next, I want a beautiful girlfriend.

- OK - the short man replies - Tomorrow you will wake up next to her.

The man is still not sure whether to believe him, but he continues.

- I want a penis as large as yours.

- Alright, but there is one catch - the short man replies.

- What's that - the man asks?

- I have to have sex with you from behind - the short man says.

The other man thinks for a second, and decides anything is worth getting a penis that large.

- OK, go right ahead.

The short man starts to do his thing, and the other man says:

- I can't believe I'm gonna have a penis as big as yours.

The short man replies:

- I can't believe you thought I was a leprechaun!
