Breakfast Cereals

"I remember a commercial were a martian confronts an astronaut and says "Greetings earth man take me to your CLACKERS!" or something like that. My brother and i never forgot it."

"Really? (to reviews below) This is one of my favorite cereals of all time. I buy it at the store even when I don't need it, just to encourage sales so that Kellogg's will continue to make it. I absolutely love this cereal, and I am a considerable cereal consumer (Cap'n Crunch and Frosted Flakes being some of my other top choices)."

"I assume it was the same Double Chex - but I remember one from the early 90s that had twins singing "I I love love double double chex chex, better better than than the the rest rest. Wheat wheat rice rice double double crunch crunch. Crackle crackle crisp crisp bite bite munch munch.... It's lightly sweetened!" (repeat)"

"Here-here. Love this. Where has it gone???"
