A donkey walks into a bar and sits down next to a really attractive young lady, orders a brew and turns to the young woman and asks her "Do you date asses?"
The young lady thinks for a while about the men in her life and why she was sitting here in a bar all alone...... She responds "As a matter of fact I do."
The donkey takes a long drink of his beer and then stands up and turns around and says "Great! How old is mine?"
