Best: Ipod
Worst: A globe. I can't tell you what a thrill it is to be 8-years-old and get a globe. My aunt struggled under the delusion that smart kids always want educational toys, and not the good educational toys (like maybe "put together your own weather station", but the boring educational toys (so what does this do again, sit there - nope, wait, you can make it spin...).
I would have much rather gotten something Barbie-related, but nope, I got something that was actually out of date within a very short time (wars, countries breaking up, new ones forming, etc - hey everyone, look, the Soviet Union! ...whoops, wait, too late, thats gone now...)
My sister fared worse from her - one year she got a "Zok", which was a sock, with a clay face stuck into it, and it was supposed to be to save money in. What it was is a very trashy tacky tourist souvenir, and not an appropriate gift to give a child. My sister still talks of the Zok.
