Here's something.... in the 70's (I think) there was an actual breakfast cereal that had bits of freeze dried ice cream floating in there. Could you imagine the conniption fits parental groups would have today if they even suggested it?
You know what cereal I miss like crazy? I know it was only a limited time promotional thing for a movie... but I miss Atlantis: the Lost Cereal. It was like Lucky Charms... but instead of the solid rock hard marshmallow bits, it had small chocolate cookies.
Ajnd, while it was the most artificially tasting and colored cereal, I miss Buzz Lightyear bits. That was the freakiest colored thing I ever seen... Green cereal pieces with purple graham crackers shaped like the L.G.M.s.... Though, frankly... that seemed more like XR's cereal.
