Penn & Teller's smack-down of the anti-vaccination movement

I don't generally post profanity here (be warned) but this Penn & Teller Bullshit episode is just too good not to post. The cynicism informed by stupidity of the anti-vaccination movement gets an in-your-face response. But despite being in-your-face the video captures the nuances of the controversy and gets the science right. Very effective.
