I think this commercial clip actually comes from an episode of The Tonight Show when Jack Black was a guest. That would explain the audience laughter heard when a young Jack Black pops up on the screen. The commercial is for Pitfall, one of the best Atari games ever. Pitfall helped me improve my running, jumping, swinging and falling-into-things skills. Also, it taught me that if you stand on a crocodile's head, it can't eat you. Also the best way to avoid a rattlesnake is to run straight at it and jump over it. If I ever become lost in the jungle, I should be able to survive with no trouble at all.
