Oh man, Ivan's message reminded my of a famous picture I was in when I was a kid (or so I thought). I had a little badge of Drew Barrymore in ET wearing this stripy skivvy/turtleneck top, of which I happened to own one which was almost identical. I was about the same age as her at the time I owned it, and was utterly convinced it was me... and that somehow I'd met ET, had a photo taken and then completely forgotten about it.
Well, that sort of stuff happens when you meet aliens, doesn't it? They take your memories.
