Babies have very weird senses of humor.

They can't get enough of peek-a-boo and yuk it up when something innocuous happens, like a doorbell ringing. Yet, put on an episode of 'Modern Family' and...nothing!

The peculiarities of what exactly a baby will laugh at is further illustrated in this cute clip, in which a tyke named Austin simply can't stop laughing at his dog eating from his bowl of food.

Cute kid? Check. Innocent animal? Check. Yes, it's official -- this is a video tailor-made for the Internet.
