today, i looked at someones avatar at tank-net (a tank forum.. duh)
looking at it, i was able to identify it as a T-55 turret seen from the top, taken from a book about the T-55 in the osprey series of "tanks in detail" books.
i had only briefly shuffled over the pages with the picture about half a year ago, but still it was a solid ID.
this is completely pointless information that i've managed to memorize, without even trying.
so i ask, whats the most useless stuff you've ever memorized, and does anyone have a clue why minor things like these things stick to your mind like glue?
