ahoy there, mates

My favorite commercial on TV right now. Spoilers below:

It's a Chips Ahoy commercial. Sort of animated, I don't know how to describe it. But the point of the commercial.

There is a birthday party for a little girl and she and her guests are sitting around the table with a large cookie next to the children. He says, "Where's the cake?" The birthday girl answers sweetly, "We're not having cake." The cookie answers weakly, "Oh..."

It's funny, but what I like the best is the intonation/inflection of the girl's answer. It cracks me up. I know, I'm weird.
