A local bar was so sure that its bartender was the
strongest man around, that they offered a $1,000
bet for anyone to prove them wrong. 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 from the
lemon, would win the money.

Many people tried to win the bet over time
(weightlifters, longshoremen, etc.), but nobody
could do it.
One day, a scrawny man wearing thick glasses and a
polyester suit, came in and said in a tiny,
squeaky voice, "I'd like to try the bet."
After the laughter died down, the bartender
said, "Okay," grabbed a lemon, and squeezed away.
Then he handed the wrinkled remains of the rind to
the little man.
The crowd'* 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
$1,000, and asked the little man, "What do you do
for a living? Are you a lumberjack, a weightlifter, or
what?"
The man replied, "No, I work for the IRS."
