Funniest "clean" Joke Ever Told?

A man walks into a bar, sits down, and orders a drink. He pulls out a velvet sack and takes a hamster out of the sack, placing it on the bar. The little hamster runs around a bit until the man produces a miniature piano and piano stool from the sack, and puts them on the bar. The hamster runs over, sits down on the stool, and to the absolute wonder of all the people at the bar, begins to play the piano like a master.

The little hamster has done four or five numbers and in launching into “The Entertainer” when the man reaches into the sack again and pulls out a bullfrog. He sits the bullfrog down on the bar next to the piano-playing hamster. Immediately the bullfrog, with the hamster accompanying him, sings a rendition of “Danny Boy” that brings tears to the eyes of all assembled. A hundred people are watching. It’s the most amazing thing anyone has ever seen.

As “Danny Boy” ends, through the thunderous applause, a bystander leans over and says, “Excuse me, are these animals for sale?”

“Well,” says the guy with the animals, “I’m really attached to the hamster. but I might sell the bullfrog.”

“I’ll give you five hundred dollars for the frog,” says the other man.

“Sold!” says the animal guy, and he hands over the frog and takes his $500. Then he starts to pack up the hamster and the piano in his sack.

The bartender leans over and says, “Look, buddy, it’s really none of my business, but just five hundred bucks for a singing frog? It’s the most amazing thing in the history of the world and you didn’t even get enough for a good suit. Are you crazy? You got totally ripped off!”

The guy says, “No, I didn’t. The hamster’s a ventriloquist.”
