First of all, for those of you who've ever owned a cat, you will understand this one...
Lap Dance
Here's another cat one, it's actually a windows media file, but it's worth the effort to watch it.
Funny Cats
A quick fun animation to a muppet song...
Manamana...
And this is only worth it if you know the plot of Romeo and Juliet. They translated it into 1337, basically, and if you know the plot, it's worth it and VERY funny, but if you don't really know it, it may be a little long....it's a whole play for goodness sake! Still, I REALLY recommend it....
Romeo + Juliet L33T
Have fun...
