So this dude is auditioning to play piano in a bar. He plays an amazing song and the bar owner is all, "Great song. What's the title?" And the pianist says, "Yank her panties off and bang her doggie style." The owner looks disgusted and says, "Okay, play me another song." So he plays this great song and the owner says, "Awesome song, what's it called?" And the pianist says, "Stick your dick in her mouth and shoot your load down her throat." So the bar owner says, "Look, dude, I really love your music, but I can't stand the titles of your songs. So I'll make you a deal. You can have the gig, but you can't tell anyone the titles of your songs. So the piano player agrees to that.

That night he's playing for the crowd and everyone's loving it. Then he takes a break to go to the restroom. When he comes out, someone approaches him and says, "Excuse me do you know your fly's open and your dick's hanging out?" The pianist beams with pride and says, "Do I know the song? Man I wrote it!"
