Short animation - men lined up near a cliff

There was a short animation, i guess from the 80's, about a group of men lined up side by side next to a cliff. One man uses his elbow to touche the next man, then this touched the next and so on, until it reaches the last one that was on edge of the cliff and then falls. Then, everyone takes one step to the side and it begins all over again. In the middle there was a comical character that ruined it all.
Anyone remembers that? What was the name of this short animation? Who was the author? I had the idea that it was an american short by Bill Plympton but i'm not sure and i cannot find it on the anywhere.
