I remember people suggesting that music videos would never make it because they were just visuals added to the same music available already.

For me, the audio makes is a completely different experience: just hearing its voice say "nap time" alone was very intense. When I watched this, I blew coffee on my desk and looked around guiltily. The comic caused no such reaction.

At youtube, there are 3 versions of this "animated" comic, and one is more animated, but does not contain all the original comic panels. I thought this one was a more honest homage to the VG cats comic, but that's of course a heavily personal opinion.

There's a hilarious comic by VG Cats on the topic of facehuggers. I always found things that attach to people's heads - facehuggers, headcrabs, hats - to be very creepy.
