American Ninja Warrior is a television show about an obstacle course of the same name. Completing it, let alone doing so quickly, is an incredibly difficult task requiring great strength, endurance, and dexterity.
Yoshi, who looks about 2 years old, is obsessed with the show. So his father set up an obstacle course in the backyard. Watch Yoshi smash through it, clearing every challenge.
Bonus item: Matt Iseman, the host of American Ninja Warrior, was so impressed with Yoshi that he provided a voice over commentary of Yoshi's run. You can watch it here.
