This might be the best laughing baby video ever. Not just because it's cute, but because there is also a sinister, diabolical quality to this infant I've never seen before.

I'm not sure if the baby is a boy or a girl (I'm going with boy based on the blue-ish pillow), but the evil troll laugh on this guy is awesome.

All of my kids just had cute baby laughs. Nothing like the "muah-ah-ha-ha" thing this guy has going on.
