Mike O'Malley, currently a recurring player on My Name Is Earl, has been cast as a friend and coworker of Christian Slater's on NBC's My Own Worst Enemy, premiering this fall.

For those just tuning in, Slater stars as a soccer dad who comes to realize he moonlights as a superspy.

Funny story - spellcheck just saved me from calling the show "My Own Worst Enema" (which is actually a reality series NBC has planned for next spring). - MWM
