Tell me the funniest joke.

There is a penguin whose home is far from the polar bear's home. It will take 20 years to get there on foot. One day, the penguin stayed at home and was bored. He was going to play with polar bears, so he went out, but on the way, he found that he forgot to lock the door. It's been 10 years, but the door still has to be locked, so the penguin went home to lock it. After locking the door, the penguin set out again to look for the polar bear, which means it took him 40 years to reach the polar bear's home ... Then the penguin knocked on the door and said, "Polar bear, polar bear, penguin wants to play with you!" " "

Guess what the polar bear said when he opened the door? ..... "Let's go to your house to play ~"
