What's the joke between polar bears and penguins?

It is said that 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, Penguin was particularly bored at home, so he went out to play with polar bears, but on the way, he found that he forgot to turn off the gas at home. It has been 65,438+00 years, but the gas still has to be turned off, so the penguin went home and turned off the gas. After turning off the gas, 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!" " "As a result, after the polar bear opened the door, guess what he said ..." I won't play with you! " "

..... "Let's go to your house to play ~"

As a result, the polar bear shouted to the outside without even opening the door this time: "I don't play!" " "

As a result, the polar bear was not there, and the neighbor seal told him that the polar bear had just come home yesterday, saying that he had forgotten to turn off the refrigerator, and had set off to play with penguins today.

This is a cold joke.
