Show Lo invented a cold joke at Happy Camp, didn't he?

It is said that the word cold joke comes from such a classic cold joke: one day the little penguin asked his grandmother, "grandma, grandma, am I a penguin?" "Yes, of course you are a penguin." The little penguin asks his father again, "Dad, Dad, am I a penguin?" "Yes, you are a penguin. What's wrong? " "But, but why do I feel so cold?" There is another version: A polar bear stays in a daze on the ice, and when he is really bored, he starts to pull out his own hair, one ... two ... three ... but he doesn't pull out the last one, and suddenly shouts, "It's so cold! ! "Then a penguin began to pluck his own hair one by one ... finally, there was none left. He said to the polar bear, "It's really cold! ! "People will tell this joke: It's cold. Then slowly, the word "cold joke" came into being.
