While we're talking money--did you hear about the young man went to New Orleans, stopped in a bar, ordered a drink, and put a $20 dollar bill on the bar. The bartender served the drink, took the $20, but an $18 bill on the bar.
The young man said, "hey that's no good". The bartender said, "sure it is, you take this to any bar or shop on this street and it's good.
So, off he went. Stopped in another bar, asked the bartender if he'd change the bill. The bartender said, "sure, how do you want it, 2-$9s or 3-$6s.
GONG, huh? ;-)
