Who has heard the cold joke about Mosquito's birthday?

It is said that a mosquito flew into a man's hand, sucked a lot of blood, and was found by this man, who was about to shoot him to death. The mosquito said, "Big Brother, Big Brother, don't shoot me. Today is my birthday. " "Oh, your birthday, just clap your hand and say happy birthday to you, happy birthday. . . . . "
