Muhammad Ali, the great wrestler was never known for being a kind person. Once he was on an airplane and he often said, “I'm the greatest.” The airhostesses looked at him and saw he didn't have his seatbelt fastened. She said to him, “Mr. Ali, you'll have to fasten your seatbelt.” Ali responded, “Superman don't need seatbelt.” The hostess then replied, “Superman don't need airplane either.”
