Ask for a joke that can make people laugh.

The Arab student sent an email to his father: "Dad, Berlin is a good place. People here are very friendly. But I'm a little embarrassed to go to school. When everyone else goes to school by subway, I will drive a pure gold Mercedes. " Dad wrote back: "son, I transferred 200 million dollars to you." Don't embarrass me, go and buy a subway! "

Anyway, I laughed heartily, hehe
