Don't you hate it when you let a kid you were supposed to be watching drown because you were smoking pot? The folks responsible for those hilarious commercials have now produced equally hilarious "bad things happen" stoner greeting cards. They're even funnier after a spliff. (Hat tip: Jenn Holland.)
Incidentally, why aren't they running these ads for alcohol? I'd be much more worried about a drunk babysitter than a high one. And while I might be a little nervous riding shotgun with a stoned driver, I'd be terrified riding with a drunk one.
