Hat tip to Boing Boing for unearthing this marvelous 1950s-era PSA, in which actor Raymond Massey GENTLY but FIRMLY urges the American public to be wary of fraudulent "medical" cures. Sorry, folks, but there are no Z-rays, and music can't cure cancer. Not even Outkast's.
Can we update the expression "doorbell doctor" for the Google/infomercial age? Because I think we need it.
