Remember When "Bewitched" Cured Racism With Blackface?

I have a soft spot of cheesy 50s/60s sitcoms, which definitely includes "Bewitched," but I don't know that I'd ever seen THIS episode before; which features the Stevens Family encountering a Christmastime houseguest/potential business-associate of Darrins who turns out to be a racist. It must have been pretty eyebrow-raising to even hear the WORD racist on a sitcom back then, alongside the bonus of one a rare instance of Samantha using her powers to "get" somebody (that was usually more of an Endora or Serena thing) - in this case zapping the bigot so that he sees everyone around him as black... and yes, the effect is accomplished by putting the "regular" white cast in tan makeup:



Yeah. The blackface is HILLARIOUSLY terrible. But Sam's final pre-commercial break zinger? How the HELL did that make it to air on network TV at that time?
