Money for nothing...
I did my laundry today. The two upshots to that are: tomorrow I'll get to wear underwear and while doing my laundry I got some free money. When I was at the laundromat I decided to try putting a Hong Kong 1 dollar coin into the washing machine just to see what happened. I figured if anything it might mistake it for $10NT as they're about the same size. Imagine my surprise when it mistook it for $50NT. At a current exchange rate of 1.00 HKD=4.19275 TWD that's a pretty good rate of return. If you're living in Taiwan, I recommend bringing back some $1 coins next time you fly throgh Hong Kong. That is, unless you have a moral objection to this sort of thing. In which case you can leave the coins in HK, or better yet give them to me.
