The Leprechaun

A man walks into a bar after a long day of hard work. He sits at the bar and orders a few drinks.
While drinking a leprechaun comes up to him and asks " Why do ye look so gloom?" then man tell him the stories of his days encountsers.
After a while the leprechaun makes the man a proposition, "I'll tell ye what, if you take me into the back room and fuck me in the ass I'll give you me pot of gold!"
The man hesitates for a moment and finaly agrees that he has nothing to do so the 2 walk into the back room and the man begins to screw the leprechaun.
During all this while the man is huffing and puffing away the leprechaun asks the man, "How old ye be?" the man replies "I'm 36". After a moment the leprechaun replies by saying " You're 36 and still believe in leprechauns?"
