Madge the manicurist, telling her client “You’re soaking in it” (the “it” would be Palmolive dishwashing liquid).
I don’t know if this was effective in selling Palmolive; I do know it was widely mocked in the 80s.
What’s interesting to me was finding a UK version with a different Madge. (Note that in the UK, they don’t rinse dishes, just put the soapy ones in the drying rack.)
