What's the funniest joke you've ever met?

A man is frustrated in literature and art, his parents are sick, his family is poor and his wife is fat and ugly. When I was frustrated, I met the lamp god. The lamp god said, write down your wishes and I will satisfy you. The frustrated man wrote, "May the family be rich, the parents be healthy and the wife be beautiful." Depressed people rushed home and saw the house become magnificent; Open the door, parents are tough; I ran into the room and saw an air conditioner on the bed.
