Good to the last drop
The local bar patrons were so sure that their bartender was the strongest man around that they offered a standing $1,000.00 bet. The bartender would squeeze a lemon until all the juice ran into a glass, then hand the lemon to the bet taker. Anyone who could squeeze one more drop of juice out of the lemon, would win the money.
Many people had tried over time, (weight lifters, longshoremen, etc.) but nobody could do it. One day this scrawny little man came in, wearing thick eyeglasses and a polyester suit, and said in a tiny, 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. He then handed the wrinkled remains of the rind to the little man.
The crowd's laughter turned to total silence as the scrawny little man clenched his fist around the lemon and six more drops fell into the glass. As the crowd cheered, the bartender paid the $1,000, and asked the little man, "What do you do for a living? Are you a lumberjack, a weight lifter, or what?"
The little man replied, "No, I just work for the IRS."
