Just before takeoff one day, a flight attendant approached Muhammad Ali and asked that he fasten his seat belt.
“Superman don’t need no seat belt,” Ali growled.
“Well, Superman,” the stewardess replied, “don’t need no airplane!”
The Super Fight was a fictional 1970 boxing match between Muhammad Ali and Rocky Marciano. At the time, Ali and Marciano were the only undefeated heavyweight champions in history and fans often debated who would win had they met in their primes. Ali and Marciano were filmed acting out every possible scenario in a fight and the result was then determined using probability formulas entered into a computer. The final fight was only shown once in selected cinemas around the world and later released as a DVD.
