A man goes into the bar, orders a beer, and sits near the piano player. The Piano Player, a well-renowned animal lover has a tiny monkey on a leash that bounces around as he plays standards and oldies

The man waits until the end of the song, goes to the Piano Player, and says: “Do you know that monkey just peed in my beer!”

And the Piano Player says: “No, but if you hum a few bars I’ll fake it…”
