Eh, you find it in business too. "You can't do that! I was told that someone tried and it didn't work." Of course, nobody knew who "someone" was, they'd just been told the same story themselves and took it as gospel. I got it to work.
A few seconds of this and I realized it was done by Jay Ward Productions (Rocky & Bullwinkle, George of the Jungle, Quisp and Quake cereal commercials...)
Ditto. I like Life/Rice Chex. I remember liking those little variety packs as a kid, where you could open the side of the box & pour the milk in. The worst were plain corn flakes, Grape-Nuts & Cream of Wheat which were always in supply at my Grandparents.
