Things to know before watching the video:
The game is cow racing - you hold the Wii-mote sideways and tilt it to steer your cow around the curves, move the Wii-mote up suddenly to jump over obstacles, and purposefully hit other things for points
Naomi's cow is on the top half of the screen, Asher's cow is on the bottom half
Isaiah thinks he's playing, but he's not
Watch the bottom of the screen to see that Asher is making his cow just jump, jump, jump. Not a good strategy if you're trying to win the cow race, but very good if you think it's hysterical to see a cow jump repeatedly.
