Have you seen this hilarious video? Some guy in Florida is training for the show "American Ninja Warrior," you know, the one where you have to run through the crazy obstacle course while viewers from home wait for you to smack against a wall and fall into the cold water below.

Not only did he ROCK this practice course, but he did it in a Tyrannosaurus Rex costume. 

I guarantee you'll at least GIGGLE at some point through this video….just watching the little arms and invisioning this being a real animal taking on the ropes and barrells makes me lose it every single time!
