Senior quarterback Hymie Vincible charges out from the half-time locker room talk, through a sign welcoming the team back to the field. Unknown to him, opposing cheerleaders have substituted a thin plywood sheet for the original paper one, so Hymie is slowed as he breaks through it.

Basic concept is the impulse-momentum relationship:
