New Zealand paper money isn't even made of paper. It is plastic, and had a little see-through window in it. (gets up to find money...)

(after lengthy search...) OK, the best description I can give:

New Zealand plastic paper money smells like airports. What does an airport smell like I hear you ask? Well, I guess it smells a bit like a room full of 20s.

Hmmm, is there a node about the indescribability of smells?
