Big surprise here.
Still, these were heady days in early nerd culture. A big time breakfast manufacturer built (successfully) an entire line of cereals based on old monster movies, figuring kids liked monsters, and that at least a percentage of them (along with their parents) would recognize ersatz voices based on Lugosi, Karloff and Lorre.
I know these are back out for Halloween, I may have to grab myself a box of Booberry for old time’s sake.
