So the 'shmen were allowed to dance around and formed a swirling "68" for the delighted Harvard stands.
Afterwards, in an act of unexpected bravado, they decided to climb into the Harvard stands and sing their Alma mater, a tradition usually reserved for home contests.
But there they faced an obstacle far more vicious than the University policemen.
The Terminator.
A middle-aged fat guy with a decent forehand, the Terminator wielded an open umbrella to beat back the green-clad horde. Finally, one resourceful 'shman took his umbrella and he didn't give it back.
Triumphant, the 'shmen sang their song and returned to the visitor's side of the field.
The policemen, defeated by an unruly mob, were nonetheless lauded by Johnson.
"They were specifically there to preserve and protect public order," he said. "They acted correctly."
As the halftime entertainment drew to a close, the Harvard and Dartmouth football teams--unaware of the intermission antics--took the field to continue their gridiron battle.
But the real confrontation--a conflict between spirit and reason--was over. And Green spirit won.
Hail the victors.
