Crew team

Yeshiva University decided to field a crew team. Unfortunately, they lost race after race. They practiced for hours every day, but never managed to come in any better than dead last.

The Rosh Yeshiva finally decided to send Yankel to spy on the Harvard team. So Yankel shlepped off to Cambridge and hid in the bull rushes off the Charles River, from where he carefully watched the Harvard team as they practiced.

Yankel finally returned to Yeshiva. "I have figured out their secret," he announced.

"They have eight guys rowing and only one guy shouting."
