Oddly, I openly collect teddy bears. Most people know this (very few know about my AB tendencies). Oddly, once people find out you collect things, you tend to get more of them. I end up with a whole lot of teddy bears (a couple from my straight-laced speaking-in-tongues pentacostal sister in law).

I was collecting religious texts for a while (as they said on House, MD, I want to know what people are doing wrong). This got me a few things added to my collection (like a Koran), but one day when the WorldCon was at a Mariott I suddenly found myself the recipient of a dozen copies of the Book of Mormon that my friends lifted from the hotel and sent me.

I also collect glass paperweights and a few other things I can leave sitting out in public
