This is a game from likely the 70's or 80's. A board game similar to Mouse Trap in that, you set up a bunch of precarious pieces, and at the end the sequence is triggered and all the pieces jump or spin or do whatever they do. Except this game involved a circus I think. I recall 2 circus performers spinning around a pole, opposite each other, from the top downward.
It is a fleeting memory, and has been bugging me for years!
