So many...
One year I got thongs (as in the kind for your feet). I never wear thongs. It's hurts. But I took them regardless. Then the next year I got more thongs.
One time I got a wallet, and I already had a wallet that was much better (my cards and money actually fit inside). Then the next year I got another wallet. At least the second time it had five dollars in it.
I once got an action figure from my friend. That lurked in the closet for a good few years before going to Good Sammy.
Encyclopedia Britanica. Probably not bad in itself, but it doesn't work properly on the computer, and we already have two sets of regular encyclopedias anyway.
The cake taker though, is the random assortment of stuff that I got one birthday from my sister. Just a big pile of stuff you'd find in a two dollar shop. I remember it had water balloons, sparklers, a t-shirt that didn't fit the person it was originally meant for, a rubber snake, some fads, some fizzers. All useless shit.
I also remember giving some crappy stuff. Like buying one of those CD's with all of the years Top 40 chart Number one's for my sister's boyfriend because I knew he was a DJ. Thankfully my sister stopped me and advised me to switch to a Ministry of Sound CD, which I did.
Also I once gave my dad a shoe brush, because I noticed that he sometimes polishes his shoes. He liked it (I think) but I should have put a bit more thought in.
All of these are back when I was eight or nine years old, just to put it into some perspective (Except for the crap pile, that was on my 14th birthday).
