A bulldog. A ball. A string. The elements of this perpetual motion machine are simple, and yet it's the only one we've ever seen that made us LOL.
As if being a cute video weren't enough, the YouTube uploader thinks this non-stop ball-chasing experiment could be the answer to one of our biggest problems:
"This cute bulldog could solve the world energy crisis if only we could find a way to harness his power."
While that's an intriguing thought, we're more inclined to agree with the most popular YouTube comment on the video right now, below, which we think uses just the right amount of capital letters and punctuation for the excitement you feel after watching it:
"AWESOME VIDEO WHAT A CUTIE PIE DOG WONDERFUL FUN LOVED THIS VIDEO FAVORED IT TO AMAZING 100 THUMBS UP 5 STARS TO THIS SWEETIE"
