In Muhammad Ali’s heyday as the heavy weight champion in boxing, he had taken his seat on a 747 which was starting to taxi down the runway for take off. The flight attendant walked by and noticed Ali did not have on his seatbelt, and said, “Please fasten your seatbelt, sir.”
He looked up proudly and snapped, “Superman don’t need no seatbelt.”
Without hesitation she stared at him and said, “Superman don’t need no plane.”
