This has never been done before,and was WAY ahead of its'time,but in the episode where Lucy went to Italy at the invitation of an Italian movie producer,who hires her if she can "soak up some local color"(much against Ricky's wishes),and gets into a fight with a local Italian woman in a grape wine vat,where she gets "color",covered head to toe with grapes.Well,anyway,she returns to the apartment in Italy,and learns that the producer who promised the part to her,gives it to Ethel,instead.Lucy says something under her breath,and it is CENSORED.Anyone notice this?

I think it's a joke. Lucy is mad and she's "cussing." (Probably not for real, though.)

If you look at her mouth while she is "swearing", she's just sayin jibberish. She's not saying anything real. At least, not any of the swear words i kno.

Yes, it's just a joke.
