Er... Mabel and Dipper were just cooking. Dipper got splattered with ketchup, and Mabel was cutting onions. Now they're tired and Dipper fell asleep. Mabel is hugging him because she's happy with their work. They've made a nice pizza, and Grunkle Stan is going to love it.

I mean, that's what this picture is about, right? Riiight? Please...
