A dad walks into a market with his young son. The kid is holding a quarter
coin. Suddenly, the boy starts choking, going blue in the face. The dad
realises the boy has swallowed the coin and starts panicking, shouting
for help.

A well dressed, attractive, but serious looking woman in a blue business
suit is sitting at a coffee bar in the market reading her newspaper and
sipping a cup of coffee. At the sound of the commotion, she looks up,
puts her coffee cup down on the saucer, neatly folds the newspaper and
places it on the counter, gets up from her seat and makes her way,
unhurried, across the market. Reaching the boy, the woman carefully takes
hold of the boy's testicles and starts to squeeze, gently at first and
then ever more firmly.

After a few seconds the boy convulses violently and coughs up the money,
which the woman deftly catches in her free hand. Releasing the boy, the
woman hands the coin to the father and walks back to her seat in the
coffee bar without saying a word.

As soon as he is sure that his son has suffered no lasting ill effects,
the father rushes over to the woman and starts thanking her saying,
"I've never seen anybody do anything like that before, it was fantastic.
Are you a doctor?"

"No," the woman replies. "I work for the Internal Revenue Service."
