Suplex the dog

One time, when Brock was a kid, he was watching the fight scene in Willow where the dogs attack the village, and he got so pumped that he tried to suplex Marty, his grandpa's poodle, and his grandpa walked in right as he was about to do it, and got hella pissed and was concerned that Brock might be a bad person. But he wasn't. He was just pumped like this old thing: Real Ultimate Power.
UPDATE: What really happened is that Marty ran into the room with "fierce virility" and Brock did what he had to do and defended the house from the invading hoard of one black poodle.
