In the beginning of the movie when Roberta comes to Chrissy's house from the grocery store she hands Chrissy a plastic bag and says "Here. Thought of Jiffy Pop thought of you. Don't go near the stove you may burst." But the plastic bag doesn't contain Jiffy Pop, it contains Breyer's ice cream, and Breyer's is clearly written on the box, It looks like Strawberry flavored, and Chrissy goes straight to the freezer to put it away.
