How did Mohammed Ali (not the boxer) defeat the much taller Dan Mannix in the competition of swallowing the longest sword?
Mannix set the standard by swallowing a 26 inch sword making sure the hilt rang against his teeth. However, the crafty, much shorter Ali ate a heavy meal weighing down his stomach before the contest and won by swallowing a sword 3 inches longer.
