An unemployed pianist walks into a piano bar and starts jamming. Th emanager runs up to him and says he's never heard anyone play that well.
"Thanks." says the pianist, launching right into another song. "I call that one 'Smell My Balls.' This one's called 'Banging a Bag Lady.'"
"Tell You What," says the manager,"come by tonight and we'll see how it goes, Just don't go announcing the names of your songs to the audience."
That night the pianist quickly gets the place rocking. After playing for an hour, he goes to the bathroom. when he returns a hush falls over the crowd.
One of the customers leans over and says,"Hey buddy, do you know your schlong's hanging out of your zipper?" "Know it?" says the pianist, excitedly, "I wrote it!"
