The local bar was so sure 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, including the professional wrestlers and bodybuilders, but nobody could do it.
One day a scrawny little man came in, wearing a tie and a pair of pants hiked up past his belly button.

He said in a squeaky annoying voice, "I'd like to try the bet."
Even the hillbilly chicks burst into laughter.

After the laughter had died down, the bartender said, "Ok," grabbed a lemon, and squeezed away. He then handed the wrinkled remains of the rind to the little man.

But the crowd's laughter turned to total silence as the man 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 man, "What did you do for a living? Are you a lumberjack, weight lifter, or what?"
The man replied, "I work for the IRS."
