This is the $8 World's Smallest Stretch Armstrong doll available from Vat19. It's like a regular Stretch Armstrong toy from the 70's, except only 4-inches tall. His arms and legs can stretch to over twice his body length, although I don't think he has that magical Stretch Armstrong goo inside, I think he's entirely latex. That's a shame too, because he looks like he'd make a great bite-size snack. "Jesus, what don't you eat, GW?" So far, only turds.
Keep going for one more shot and a video.
Thanks to gabe, who agrees it's only a matter of time until somebody makes a knock-off Stretch Armstrong sex toy provided it doesn't already exist which it probably does.
