The little penguin asked his mother a cold joke.

One day, the little penguin asked his grandmother, "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?"

Cold jokes are jokes that make people laugh. This joke is so cold that even the protagonist (the little penguin feels cold) says it is a good cold joke.
