Biography
In "A.D.D.: The Last D is for Disorder" (his only major appearance), he meets Abe Lincoln while working at the A.D.D. Education Institute. Abe tells him about Clone High's mistreatment of his friend Gandhi due to his A.D.D., to which Green replies (in-between crude, vulgar non-sequiturs) that such treatment would fall under discrimination. He then promptly flings himself out of a window. Later, he attempts to educate the students of Clone High about A.D.D., but his speech is quickly derailed and he leaves in pursuit of a plastic bag being carried away by the wind.
His second, and currently last, appearance is in "Changes: The Big Prom: The Sex Romp: The Season Finale", where he makes a cameo appearance during the conga line near the end of the episode.
