This guy walks into a bar ...
He sits down, and orders a beer from the bartender.
Served, he's taking a sip of his drink, when a little monkey jumps up from the floor, onto his lap then onto the bar, and holds its hand out, obviously begging for change.
The guy is a bit taken aback, and flicks the monkey's hand away. The monkey looks at him, with small malevolent eyes, and moves back a bit. A short while later it grasps its little penis then proceeds to let out a stream of golden piss, right into the guy's beer glass and all over the bar.
Outraged, he calls over the barman (who has seen the entire display, and is stifling a smirk as he wanders over, with a cloth to soak up the mess)
Guy: "Is that your monkey?"
Barkeep: "Nah, it's the piano-player's, its how he gets his tips."
So the guy gets up from his place at the bar, face bright red, looking to murder someone for this outrage, grabs his adulterated beer, and stomps over to the pianist (who is belting out Billy Joel's Pianoman, natch), and taps the musician on the shoulder:
Guy: "Do you know your monkey just pissed in my beer?"
Musician: "no, but if you hum a few bars, I can fake it."
