Here's TammieRD's compilation of all the alternate endings to the Animaniacs theme song, each better than the last. As I mentioned before the complete seasons 1-3 DVDs are a huge hit around our house. Really some of the best kids' (and grownups') TV of the last century.
hh1edits's "The 100 Greatest Movie Threats of All Time" is a truly fabulous 11:37 worth of threatening behavior -- angry, calm, brave, terrified. The creator casts an admirably broad net, including appearances from Monty Python, Wil Wheaton, and the Wicked Witch of the West.
