This is, quite simply, brilliant. The Vaccine Song:
I have a hard time disagreeing with anything in that song*. I really wish everyone knew that at the same time Jenny McCarthy is railing against vaccines for their toxins, she was injecting botox -- which contains botulin, one of the deadliest substances known to mankind -- directly into her face.
* I'm not thrilled with the ad hominems in the song, but the point is well-taken: people would rather listen to someone like McCarthy and Carrey, who have no medical expertise at all, over their trained and experienced doctors.
