The local pub was so sure that its bartender was the strongest man around that they offered a standing $1,000 bet. The bartender would squeeze a lemon until all the juice ran into a glass and then hand the lemon to a customer. Anyone who could squeeze one more drop of juice out would win the money. Many people had tried over time (weight-lifters, rowers, wrestlers, etc.) but nobody could do it.
One day, Hyman, a scrawny little man, came into the bar wearing thick glasses and a cheap jacket. Hyman went up to the bartender and said in a squeaky voice, “I’d like to try the bet.”
After the laughter had died down, the bartender said, “OK,” grabbed a lemon and squeezed away. Then he handed the wrinkled remains of the rind to Hyman. But the laughter turned to silence as Hyman clenched his fist around the lemon and four drops fell into the glass.
As the crowd cheered, the tender paid the $1,000 and asked, “What do you do for a living? Are you a professional strong man, or what?”
Hyman replied, “No. I’m not, I work for the Jewish National Fund.”
