If you buy bunny, footed pjs, you could be the kid from A Christmas Story.
ETA: You might also fund some spiderman costume/PJs. Take a white dress, throw red paint on it, wet your hair, and go as Carrie. Bring some TP and go as the mummy. Spike your hair and go as Mary in There's something about Mary. The mask from scream and a black cape. Carry around an old video camera and go as the kids in the Blair Witch Project. Nun costume for Sister Act. Put on devil horns and slap a fake Prada label on something. Pair of boxing gloves and you're Million Dollar Baby.
Can you bring an empty ice cream container and some magazines or something ?
ooooh. Good idea!
Also, I am on the hunt for the same PJs in a larger size. I haven't found them yet, so I'm working with what I have. Which, I admit, is more fitted than PJs usually are.
