He is fourteen years old when the series begins, making his birth year 1970 . In the pilot episode, he is lectured by his father for not applying himself at school ("I brought you in this world, and I'll take you out"). Also in the early seasons, he was somewhat of a troublemaker, as illustrated through incidents both alluded to and explicitly portrayed in the series, such as letting his best friend's younger sister pierce his ear, resulting in an infected earlobe, but his behavior had improved by the time he left high school . </P>
