It's worth noting that the good folks at SimPE have made a breakthrough in putting-objects-where-they're-not-supposed-to-be. If you download their collection files, you'll be able to inappropriately place objects at whim, without having to do the file mirror dance that I used. It was done by some fellow who's name completely eludes me due to lack of consistency, so I can't tell if it's the same person, or two different people, or what.

Unpack You know where the download folder is in My Documents/EA Games/ The Sims 2/ well there's a Collections folder too. Unzip it into that
