It's difficult to think of a "best joke", there are so many of them. Recently I heard this joke...
This burglar broke into a house in the middle of the night. He knew the occupants were away, but tried to be stealthy so as not to alert the neighbors. As he searched for valuables, he heard this voice say, "Jesus is watching you."
He stood straight up and froze for several minutes, but hearing nothing, decided his brain was playing tricks on him. But all of the sudden, he heard the voice again: "Jesus is watching you."
This time he swung his flashlight around until he saw a birdcage with a parrot inside. He relaxed, went over, and said, "Polly want a cracker?" The parrot replied, "Oh I speak English." The burglar said, "Really? What's your name?" The parrot said, "Moses." The burglar demanded, "What kind of people would name their parrot 'Moses'?" And the parrot replied, "The same kind of people that would name their Rottweiler 'Jesus'."
Its a five minute long story that ends in A butt joke
Come on, let's hear it.
