>Thanks Dragan. I can't work out your quote "I won't pay the $20. This bill is a forgery. I know how $20 bill looks, and this is not it."

Well, if someone tries to bill you $213.55, that's a $213.55 bill he's given you, right? Now if the amount was $20.00, it'd be a twenty dollar bill - and there's probably a law on how a twenty dollar bill has to look. If it doesn't look like that, it's counterfeit.

Just trying to find a home for some poor puns.
