This cute little kid is 7-year-old David, who is seen here rambling after a trip to the dentist to remove an extra tooth. His dad filmed this after noticing that David was very out of it after his surgery, presumably because David was still under the effects of medication or anesthesia. [via]
This kid is an internet star! And the end is the funniest part!

HAHAHAHAHAHAHAHAHA!
Is this real life? haha
