Punch drunk

With a Filofax punch, you can punch holes in almost anything and stick it in your organizer. I tend to take that advice literally. Here are a couple of the more unusual things I've punched holes in lately:
- Map to my dentist's new office. He sent a letter with the change of address, and I placed a sheet from my Filo over the map, traced around it, cut it out, and punched it.
- A postcard from my mother of a creche she visited in NYC in December, 2006. It was set up at MoMA. I put it in my organizer to remind myself to try to see the 2007 version of the MoMA creche.

What have you punched?
