I have an old puppet of animal from the Muppets. He's wearing a skateboard shop shirt and has a little skateboard. Just the sort of thing you could picture sitting in a window in the late 70's.

My oldest was FUCKING TERRIFIED of the puppet out of nowhere when he was like 5. He wouldn't sleep unless we could prove that it was no longer in the house.

You just never know what's going to make a formative memory until it's far too late.
