Bold Commercial
Proctor & Gamble always had campy ads for Bold, with women singing about the way Bold gets clothes bright. (Disclaimer: My mother used Bold for years; it was the only detergent she allowed in our Kenmore automatic! Me, I preferred Ajax!)
The JoAnne Worley (God, I love the woman!) spot Laundress displayed appeared on a 1968 episode of "The Mothers In Law," which was sponsored by P&G. (It's in my commercial collection, along with a 60 second version of the same ad that originally aired on "The Smothers Brothers Comedy Hour.")
Speaking of "Laugh-In" stars doing spots, Lily Tomlin also did an ad for All detergent, where she wore a dirty shirt and the set filled up with water as she added the All ("now with bleach, borax and brighteners") and the shirt came out clean! From what I remember, the FTC wasn't too happy with Lily as a human agitator and the spot was eventually pulled.
