The local bar was so sure that its bartender was the strongest man around that it offered a $1,000 bet no one could squeeze a single drop more from a lemon the bartender had already squeezed. Men from almost every walk of life had tried and failed.
One day a scrawny little man wearing thick glasses and a polyester suit walked into the bar. “I’d like to try the bet”, he said. After the laughter died down, the bartender grabbed a lemon and squeezed the juice. Then he handed the wrinkled remains to the little man.
The crowd’s laughter turned to silence as the man clenched his fist around the lemon. Six drops fell into the glass! The patrons erupted into cheers.
As the bartender handed over the $1,000, he asked what the little man did for a living. “I work for the IRS”, he answered.
