If you haven't seen the video of the drugged-up kid laughing while his broken arm is being re-set, check it out here. But I dug up another gem that might be even better:

It's from 2010, and features a confused girl who just had her wisdom teeth out. Apparently the drugs they put her on messed with her short-term memory, because she keeps repeating the same questions:

She wants to know what's in her mouth, and her mom tells her over and over again that it's gauze. And each time her mom tells her she had her wisdom teeth out, the girl looks shocked.
