Found a lovely blog by the name of Oddee: A Blog of the Oddities Of Our World which had this post on "7 Incredible Natural Phenomena you've never seen", one of which turned out to be the the tree climbing goats of Morocco. (Actually, I had seen some of these guys before, although I might have been stoned at the time (or it might have been on tv).)
Another of the 7 is shown in the Youtube clip below. The Pororoca happens twice a year (in February and March) when the tidal bore at the mouth of the Amazon drives the "world's longest wave" upriver for miles, destroying trees, houses, and anything else in its path. Naturally, some people feel a need to surf it.
Another of my favorite posts on the site concerns "10 Real Life Superheros", and includes a long quote by a guy that goes by the name of "Mr Silent".
