Who can forget Stretch Armstrong and his enemy Stretch Monster? They still make these, I believe.. I had both of these dolls sometime between 1976 and 1980. That's the actual timeline for production of this toy... '76-'80. The original ones, I mean, shown here. I was anywhere from 6 to 10 years old. More than once too, since, after only a few weeks of abuse at the hands of me and my brothers, the rubber skin of these dolls would eventually rip open and out would seep a red gooey substance... gelled corn syrup . The wound usually started as a pin hole, or a small tear, and with continual stretching would get worse, and tear open more, until the gel was leaking out and the doll was junk. We never could figure out a way to repair one of these things, despite following the repair instructions that came with it. I remember the doll getting so stretched out and the syrup so hardened up over time that we couldn't get it back to it's original shape. So we just threw the doll out and would get another one. I've had at least two of each (Armstrong, and Monster). I got mine for Christmas. I do remember that.
The monster was the one I remember being fascinated with the very most. He looked awesome!. His green rubber skin was textured with scales... and just look at that face. I believe he was a favorite toy of mine for awhile. Because he really stands stronger in my memory than Armstrong.
These dolls would stiffen up when cold, or with age, and if you submersed them in warm water, it would soften them up again. I remember it being a heavy toy (as a kid) and a good toy to strangle someone with, as we were always stretching their arms and legs to great lengths and then tying the limbs around our necks.
There's an entire website devoted to the classic stretch figures, called "Stretch Armstrong World". Plaid Stallions has some cool Stretch Armstrong material also.
