Panel 1: We start things off with a shot of the Pattersons' hoverwagon zooming down a country road past a stand selling pumpkins. One of the children reminds John that they've already passed four stands by and asks him when they're going to stop.
Panel 2: They screech to a halt at the next stand.
Panel 3: Now that they're out looking, Lizzie says "Just lookit all those pumpkins!!"
Panel 4: She reaches for one pumpkin in particular and says she wants it only to have Mike tell her that it's somehow not right.
Panel 5: She then pleads to John to buy another one only to have Mike whine that that's somehow not fair.
Panel 6: John grabs yet a third and says it's a nice one only to have Lizzie say it's too big and Mike say it's too small.
Panel 7: A little while later, we find ourselves back at the Pattermanse. Elly smiles and asks them if the three of them bought a nice pumpkin.
Panel 8: Her smile is replaced with the Goggle-Eyed Frown Of Existential Horror™ because they bought a lot of nice pumpkins. This, as fairest1 reminds us, is because she'll get stuck with the clean-up.
Summary: Experience teaches us that the most likely moral lesson that Lynn was trying to impart when she lifted this off of someone else is "Never shop with kids." This is odd because the moral lesson I derived was "If you want something done right, do it yourself!!"
