Here is a PSA that used to absolutely terrify me in the 1970s – Mr. Yuk. It got to be a love/hate kind of thing, where I'd wait for this commercial to come on that would scare me and send me out of the room. Though I did think it was pretty cool when our local poison control center came to our school and gave us some awesome Mr. Yuk stickers to place on poisons in our home!
I love reliving my childhood terrors on your site, and discovering others I hadn't known. Cheers.
