Woman tickles man's feet in peanut ad

[Backdrifter]

I wondered if anyone else remembered this tenuous ad from the late 70s/early 80s. A seductive woman tries to torture information out of a man by pulling his shoes and socks off and tickling the soles of his bare feet. When he doesn't crack, she offers him a bag of Planters (I think) dry roasted peanuts, and that's enough for him to immediately hand over the microfilm or whatever. Even at the time I thought it was one of the shakiest premises for an ad I've ever seen.
