awww that's hilarious.
Along the lines of #1 - My DD had just turned 2, and in Feb of this year she came upstairs and was watching me get dressed. I had my bra on, but not a shirt yet. She came over to me and said, "Mommy needs a seatbelt" (I almost died laughing!) Then she ran downstairs to her daddy and screamed, "Mommy's wearing a seatbelt IN THE HOUSE!! Seatbelts are in CARS"
