Yeshiva University decided to field a rowing team. Unfortunately, they lose race after race. Even though they practice and practice for hours everyday, they never manage to come in any better than dead last.
Finally, the team decides to send Morris Fishbein, its captain, to spy on Harvard, the perennial championship team.
So Morris schlepps off to Cambridge and hides in the bushes next to the Charles River, where he carefully watches the Harvard team at its daily practices. After a week, Morris returns to Yeshiva.
“Well, I figured out their secret”, he announces.
“What? Tell us! Tell us!” his teammates shout.
“We should have only one guy yelling. The other eight should row.”
