The other day, out of completely nowhere I remembered a few old margarine ads (BTW, you NEVER see margarine ads any more).
The two that I can think of was:
"If you think it's butter, but it's not, 'It's Chiffon."
Then the "Duh, duh, duh, da!!!!!" And it was an Imperial Margarine commerical. The idea was you'd take a bite of something with Imperial Margarine on it and a king's crown would mysteriously appear on your head!
What old food/products can you remember now that you miss from childhood?
