"Rowing Team" joke
Yeshiva University decides to field a rowing team. But they lose race after race. Even though they practice and practice for hours every day, they never manage to come in any better than dead last.
Finally, the team decides to send Morris Fishbein, their Captain, to spy on Harvard, the perennial championship team.
So Morris schleps off to Cambridge and hides in the bushes of the Charles River, from where he carefully watches the Harvard team at their daily practice.
After two weeks, Morris finally returns to Yeshiva. "Well, I figured out their secret," he announces.
"What? Tell us! Tell us!" his teammates all want to know.
"We should have only one guy yelling. The other eight should row."
