A big-city counterfeiter decided the best place to pass off his phony $18
bills would be in some small hick town.

So, he got into his very expensive new luxury car and off he went. After
driving for a while, he found a tiny town with a single store.

He entered the store and handed one of the bogus bills to the man behind
the counter. Can you change this for me, please? he asked.

The store clerk looked at the $18 bill for a short time, then smiled and
said to the man, Ah reckon so, Mister. Ya want 2 nines or 3 sixes?
