When I was little, my parents for some reason owned a hardback volume of the Guinness Book of World Records (not just paperback, but the hardback version), and I coveted that thing like mad. I would find somewhere to go that was far away from everyone else, and I'd just pore over the pictures, sometimes for the 13th or 14th time.
I've always been in awe of anomalies.
These were a few of my favorites (these are the pics as I remember them as well):
I also used to love pictures of spontaneous combustion.
You can't get any better than that really.
