Naval Engineer Richard James discovered the Slinky in 1943 after he accidentally knocked over a spring and noticed how it "walked" from a shelf to a table and then to the floor. He immediately recognized the potential as a kid's toy, and the rest is history.

We all remember the first time we got a Slinky and watched in wonder as the metal coil navigated a flight of stairs. But how about this? A slinky on a treadmill. We just blew your mind, didn't we? Check it out.

When toys work out they listen to DJ Unk, apparently. What's so impressive about Mr. Slinky is how dedicated he is to staying on the exercise equipment. He's going to lose that weight in no time.
