Smuckers markets a ready-made peanut butter and jelly sandwich. Because spreading PB and J on bread is suck a chore. Oscar Mayer markets a microwave hotdog on a bun. Because micro-waving a hot dog and putting it on a seperate bun is such a chore. I'm surprised they haven't come up with pre-buttered toast - just stick it in the microwave and it's done. Saves you valuable seconds that you would otherwise spend in putting the butter on the bread yourself.
