Born Oct. 31, 1963, in Pacifica, Calif., Schneider began writing comedy sketches while still in high school and appeared in comedy clubs soon thereafter. In 1990, he went to work as a writer on "Saturday Night Live," eventually joining the ensemble; that exposure paved the way for supporting roles in films such as Judge Dredd (1995) and Down Periscope (1996).
It's been Schneider's friendship with Adam Sandler, however, that's led to some of his biggest films to date, including the Sandler-starred The Waterboy, Big Daddy and Mr. Deeds. More recent films for Schneider include The Benchwarmers and Click (both from 2006).
