UFC game on PS3

I was playing with my 16-year-old brother, Joaquim. He's borderline crazy. Not clinically insane, but he once proclaimed that "If I find a dinosaur, I'm keepin' it. Shoot..."
So, we were playing the game, and I was beating the hell out of him. He wasn't able to throw a punch. What I think he wanted to say was, "I can't even throw a punch." But what he said, about 30 times, sometimes yelling, was "I can't get jack off!" When said fast and loudly, it sounded like, "I can't get jacked off!" And he's right at that age where I'm not sure if I can make fun of him for saying stuff like that. So I just held my laughter in until the next fight when he was finally able to jack off.
