Ask for funny jokes, make them up by yourself or in life.

Once upon a time, a man went to shelter from the rain under a tree. Soon after, he saw a woman who didn't wear white clothes. He didn't know it was a ghost, so he ran to the female ghost and said,' What are you doing?' The female ghost slapped him in the face and he fell down and passed out. When he fainted, he saw that the woman was a ghost and he fell asleep.

But when he woke up, he saw another woman and he fell asleep again.
