Yesterdayland For all those childhood (or adulthood) memories. Contains much information on obscure cartoons.
C*E*A* The Center for the Easily Amused. But it will amuse you if you're cynical too.
Movie Bloopers Comprehensive index of all the movie mistakes that ever irked you. Plus a few that didn't.
Animal Planet From the TV channel of the same name, an amazing wifelife site.
