Swinging toilet wars

Watch two swinging toilets in action and see which toilet survives. The toilets, attached to ropes, swing black and forth until their paths begin to grow closer and closer. Why is this so much fun to watch?

Eventually they collide, and only the strongest toilet remains. Not only are the toilets swinging in mid air, they're also filled with blue toilet water.

An entire toilet swing set would be ridiculously fun.
