No, but I know the origin. There was a joke going around in the 60s. A customer went into a piano bar and sat down to have a beer and listen to the pianist perform. The pianist had a pet monkey at his side. Folks were requesting this song and that song. The customer was concentrating on the music until he reached for his beer and saw the pianist's monkey sitting on the mug, with the monkey's balls hanging down in the customer's beer. Not knowing how to react, the customer quietly walked up to the piano and at an opportune time said, "Pardon me, do you know your monkey's got his balls in my beer?" No, replied the pianist, but if you'll hum a couple of bars, I might can pick it up." Hahahahahahahahahahaha...
