An educational joke.
An American, a Japanese and a China are traveling. They met a group of cannibal aborigines and they were arrested. The tribal chief said, "I am happy today, and I won't eat you, but each of you will eat my 100 board." Before you play the board, I can satisfy one wish of each of you. " The Americans got the surfboard first. He asked for 30 mats, got the board and put it on his ass. The first 70 boards are ok, but the last 30 boards can't hold up. After the fight, the Americans are dying. What the Japanese want is 100, so it's okay. China people say; "Come on, give me a Japanese mat and put your face up.
