Eighty years ago, as Notre Dame was preparing to play the USC Trojans in college football, Fighting Irish coach Knute Rockne was aware that his opponent had a far better team. So he devised a plan to intimidate the opposing players.

Rockne scoured the city of South Bend, Indiana (Notre Dame's hometown), and hand-picked 100 of the largest men he could find—each at least six-foot-five and 300 pounds. He put the men in Fighting Irish uniforms and, at game time, marched them onto the field ahead of the real team. (Obviously, this was before the days of limited rosters and eligibility restrictions.)

As USC watched those giants line up on the sidelines, they forgot about their talent and their undefeated record, and they began mentally preparing themselves for a beating. Though none of the specially recruited men played during the game, their presence on the sidelines was enough to knock Southern Cal's concentration off balance. Knute Rockne's trick had worked; he had intimidated the Trojan players into giving up before the game even started.
