2 little elderly women had stopped into a bar for the first time in ages. Listening to the piano player, one of the ladies noticed he kept a monkey with him on the piano.

Well, unbeknownst to the piano player, (who was feeling slightly tipsy by now), the monkey was hanging himself from the top of the piano and swishing his testicles in the piano players beer which had been set on the lower edge. He was obviously enjoying that.

One of the little old ladies said, "Oh my gosh Mabel, ... look at that! Someone should tell him!" Mabel said, "Not me Martha, ... You go tell him!"

Well, reluctantly, Martha whispered in the piano players ear as he played. "Sir, ..... do you know that monkeys testicles are in your beer?"

The piano player kept playing and calmly said, ... "No ma'am, ... but if you hum it, I can play it!!!
