A Tight Squeeze
The local bar was so sure that its bartender was the strongest man around that they offered a standing $1000 bet: The bartender would squeeze a lemon until all the juice ran into a glass, and hand the lemon to a patron. Anyone who could squeeze one more drop of juice out would win the money.
Many people had tried over time (weight-lifters, longshoremen, etc.) but nobody was ever successful.
One day, a scrawny rabbi came into the bar, wearing thick glasses and a suit, and a black hat and said in a squeaky voice, "I'd like to try the bet."
After the laughter had died down, the bartender said okay, grabbed a lemon, and squeezed away. Then he handed the wrinkled remains of the rind to the little rabbi.
But the crowd's laughter turned to total silence as the rabbi clenched his fist around the lemon and six drops fell into the glass.
As the crowd cheered, the bartender paid the $1000, and asked the little rabbi, "What do you do for a living? Are you a lumberjack, a weight-lifter, or what?"
The rabbi replied "I’m the principal of a Jewish day school."
