I LOVE this story!!
I ran into the same issue with Twinkies, etc with one of my stories.
Maybe this will help some of you:
Remember in the pilot when Lois comes to pick Clark up and finds him in the towel?
Lois says: I said nine. I thought you'd be naked... ready.
CLARK says: I was on the phone. I'll be out in jiff.
Clark grabs his clothes, walks into the bathroom, shuts the door. Lois, suddenly hot, looks around, finds a paper cup, opens the tiny refrigerator, looks inside.
Inside the refrigerator Lois finds peanut butter and jelly, orange juice, Kool-Aid, root beer, etc.
She pours herself a glass of orange juice, looks around, opens the cabinets. They're filled with animal crackers, sugary cold cereals, Ding-Dongs.
This is what the script says. If I remember correctly there were also Ho-ho's and Twinkies in the cabinent.
