Making Change:

As a teenager in summer camp, I was plagued by friends cadging small amounts of money. A typical ploy went like this:
“Do you have change for a quarter?”
“Yes.”
“Good, then you can lend me a dime.” (Enough for a phone call then.)
When tired of this I tried a counter attack:
“Do you have change for a quarter?”
“Well actually, I have the largest amount of ordinary change you could possibly carry, and not be able to give change of anything.”
(After some thought) “Umm, ninety-four cents?”
“No, over a dollar.” And I would walk away unscathed, leaving them to find the answer. I worked this quite successfully several times, but I assure you I never really had $1.19 in my pocket.
