They were kinda like zip ties.
But you pulled them through a plastic thing and they said sh1t.
You could also use your fingernail and get a whole different sounding voice.
They were pretty maddening to get the speed right and keep the cadence right so you could understand what they said, but were pretty sweet.
I could very well be foggy on the details, cause most of my rememory is fried.
The reason I ask is that I fill the kid's stockings with nostalgic toys every year in hopes that that don't grow up completely retarded.
So far, so good.
