Who has a joke and tell a few more! ! !

It is said that the origin of the cold joke is such a story: 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?"
