Did Jerry ever give an explanation why he was obsessed with these two things?

I think it has something to do with muscular men it really tight clothing. haha I don't know, probably just a childhood favorite.

Cerial- Who doesn't love cerial? Cerial is the best. I would eat Golden Crisp all day, except that would be kind of stupid.

"That's the question Jimmy?"

Golden Grahams and King Vitamen were my favorites. And of course Lucky Charms.

Not sure why Jerry loved Superman, I guess he envisioned himself saving the world.

I've got to think before it's all said and done, we'll see Jerry doing his stand up tour in Superman pajamas.

I use to love the monster cereals...Frankenberry, Booberry, Count Chocula etc, etc.
