A contributor since the first season, Albert Brooks has proved to be an invaluable utility player who can come in and hit a home run when the show needs a fresh voice. As Cowboy Bob, he sold Homer a dilapidated RV that eventually plummets off a cliff, and as Jacques, a French bowling instructor, he wooed Marge Simpson when she became angry that Homer got her a bowling ball for her birthday. Most recently, he appeared in "The Simpsons Movie" as EPA chief Russ Cargill.
