Say ‘Donkey’ Around This Baby. No, Seriously, Do It. [VIDEO]

A child's laughter is so polarizing.  If you're trying to sleep and your tween daughter is hosting 12 girls for a sleep-over, the laughing can seem interminable.

But, when it's as GENUINE a laugh as this little girl has, I feel like you'd want to listen to it any time you're having a bad day.

The REALLY funny part of it is that only ONE word makes her crack up so much.  Donkey.  No other animal, no other word...just...DONKEY.
