Little brother biting this older brother and thinking it is funny til it hurts!!!!

Want proof? This kid thinks his dad is just hysterical.

This baby thinks its funny that his dad has the hiccups.

Baby in a swing laughs hysterically at someone playing with a toy.

To me, this is one of the best of the laughing baby videos I have seen. Every time his dad makes that silly noise the kid just busts a gut.

He is laughing so hard he can't even keep himself upright.
