When my little sister and I were young, we were home alone with my dad. I guess we had been suspiciously quiet, so he poked his head out of his office and found us under the kitchen table playing "lotion" with a jar of peanut butter.
We were just sitting there under the table spreading peanut butter all over our arms and legs, lol. My dad – he has a pretty good sense of humor – decided to go get the video camera (one of those old giant ones that used a full-sized VHS tape) instead of telling us to stop. and in the video I turn and look dead into the camera and earnestly say "don't tell mom!"
It's pretty awesome because I was so young that I don't have a clear memory of it, I've just seen the video enough times that I have like an artificial memory of it…and it's one of my favorites.
