Panel 1: Elly, Non-barnacle Mike and Lizzie, who's in that odd and probably anachronistic backpack get-up are passing by a store window as they watch a child about to tell Santa what he wants for Christmas.
Panel 2: They walk towards by a Santa dingle-dongling his bell for the generic charity he's collecting for.
Panel 3: As they walk by him, his presence gives Mike pause.
Panel 4: As they come across another Santa, he asks Elly why there are so many of them.
Panel 5: He points out that they saw one in the mall, one on the street and the one here.
Panel 6: Elly suggests that maybe they're ALL Santa; instead of gasping "WOW!!" like a real child his age, Mike asks if that's even possible.
Panel 7: She sets up the weak punchline by saying that the job of Santa is special as it's just like being a mom.
Panel 8: She thought-bubbles that everyone expects her to do everything and be everywhere at the same time.
Summary: We get it, already, Elly!! Your husband is a selfish jackass who thinks that you should be chained to the kitchen and your children are messy, clingy, noisy brats who want to steal your intellect and nobody will ever thank you until they scatter your ashes.
