It's Called a S'more, Moron!

I was watching "Meet the Barkers" on MTV yesterday, and toward the end of the show, Shanna tells Travis that she has a surprise dessert that she wants to make for him. She proceeds to take two graham crackers, and form a sandwich with a piece of chocolate and a roasted marshmallow.
Here in Texas we call that a s'more. It's common knowledge here. I was actually under the impression that everybody knows about s'mores. I've known about it since I was two. But Travis was like, "Oh My God - where did you come up with this?" And Shanna responds, "Just a little something I concocted."
LIAR!!!
I practically shouted at the TV, "YOU DID NOT!"
Did she just think she could take credit for the s'more and nobody would notice???
