Why wasn’t THAT advertised?!

That thing about American Gladiators(an athletic game show somewhat similar to American Ninja Warrior if it also had bodybuilders as obstacles, that ran from 1989-1996), yes that is all I knew about medicine balls. I had only seen them used to knock people down. I was very pleased to see them in their natural habitat.

The ferret finds the medicine balls and notices, "Oh, it's those things they threw at contenders on American Gladiators. That's... all I know about them."
Next panel shows the ferret hopping sideways across a mat. "I don't know if this is a real exercise, but it's fun!"
Finally, he comes to a room filled with tubes and a sign claiming they have 1000 feet of them. The ferret, in awe, proclaims, "FINALLY... the one thing I DO know how to use!"
