Hilarious video, a dad filmed his kid on the ride home after a dentist appointment. You just gotta see it:

Totally not laughing gas - laughing gas is a mix of Nitrous Oxide and Oxygen, aka whip-its, aka Nos (yeah, like the stuff that makes tricked out cars burn fuel faster), and it wears off in like 30 seconds. This kid has to be lit up from a morphine drip or something... Very funny though, my buddy showed me this yesterday!
