I was prowling the library shelves for books about the 1960s and came across one simply called 60s! by John and Gordon Gavna (New York: St. Martin's Press, 1983). I opened it randomly and saw Screaming Yellow Zonkers! (The exclamation point is part of the product name.) The snack was inspired by the Beatles' animated movie Yellow Submarine. I mentioned Zonkers! to my wife and asked her if she remembered them, and she said, "Screaming Yellow Zonkers! Mmm."
Unlike a lot of 1960s snack food creations, Zonkers! actually tasted good. They were a glazed-popcorn treat much like Poppycock and Fiddle-Faddle. But the combination of the glaze and the creative name made Screaming Yellow Zonkers! a hit for Lincoln Snacks, a Lincoln, Nebraska based company. I hadn't seen the snack in a long time and assumed it had died with the Sixties. Not so, I learned from Wikipedia. They were available until 2007, when ConAgra purchased Lincoln Snacks and immediately discontinued the line.
ConAgra needs to rethink its decision. I suspect that Zonkers! lost popularity mainly because they weren't promoted. A creative ad campaign--Zonkers! were always about creativity--could make this product a hit with a new generation, along with the millions of Baby Boomers who already love them. What about it, ConAgra?
