Funny Story

I couldn't resist posting this...can you guess what these used to be?

The story goes:

There was a monkey who liked to jump & swing, especially from handles designed for the 'Perfect Pull- Up' bar. Handles not necessarily designed for flipping and hanging from the ceiling. One day, the monkey decided to take a running flying-kung-foo-panda-like-leap onto the handles and flip upside down while rotating the handles at the same time.....CRASH!!

The monkey fell straight onto his back, head bouncing off the carpeted floor as the companion monkey looked on (trying hard not to laugh but making sure the wild monkey was okay). No lasting damage but to the poor handle bars....can you guess who the 'monkey' might be?
