Sometimes I'll say or do something cool or funny for the kids, like giving them flips or blasting them with my hairdryer or reading The Book With No Pictures. Just a one-time thing for fun. ONE-TIME. We all have a little laugh, then we move on, or at least that's what I imagine.
I should know better. If it's fun enough, it'll never be just once. The kids will want it again and again until it's long past excessive. I'll be all, "Oh, ha ha, no, that was it, just once!" or "Maybe we can open and close the garage some more later," or "if I spin you again, I'll throw up," but that doesn't get me off the hook.
Take, for instance, this recent time I thought I'd amuse my friend's kid with a one-time bit of silliness:
I never learn. If the material is any good, there'll no moving on.
PS: The Book With No Pictures is great fun, but it does involve pleading for the kids to not make you read it again, which guarantees that they will. Over and over. So if you go there, get ready to say a whole lot of "BA-DOONGY FACE!"
