One day, a man walks into a bar and sees a sign that reads, "Free drinks for anyone who can make the bartender laugh."
The man walks up to the bartender and says, "I'll have a beer and if I can make you laugh, can I get it for free?" The bartender agrees.
So the man pulls out a tiny piano and a hamster wearing a tiny tuxedo. The hamster starts playing the piano beautifully and the bartender can't help but burst out laughing.
Impressed, the bartender gives the man his free beer. The man then asks, "Can I try again for a double or nothing?" The bartender agrees and the man pulls out a frog sitting on top of the piano.
The frog starts singing opera in a beautiful soprano voice and the bartender is in stitches. He gladly gives the man another free drink.
At this point, a drunk sitting at the end of the bar stands up and says, "I bet you $100 I can make you both laugh without any props."
The bartender and the man agree to the bet. So the drunk leans in and whispers something in the bartender's ear. The bartender bursts out laughing and the man can't help but crack up too.
As they settle down, the man asks the drunk, "What did you say to make us laugh?"
The drunk replies, "I told him that I bet you $500 that I could make the bartender and the guy with the tiny piano and singing frog laugh by pulling down my pants and pretending to be a monkey. Seems like I won that bet too!"
