I pulled these out of storage recently:
I often forget that I have them. I didn't actively collect them; my father did. I had a few when I was a kid, and they ended up on my shelf when I was a teenager. My father saw them, assumed that I liked them, and started bringing them home from work. I've considered donating them to charity as they spend more time in the closet than anything, but I just can't bring myself to part with them.
