Mr. Monk Meets Dale the Whale

S1, E4: San Francisco judge Catherine Lavinio places a frantic call to 911: there's an intruder in the house trying to kill her! As the 911 operators rush to dispatch a unit to the scene, the call is cut off, and Judge Lavinio is later found dead. The cops' prime suspect is 800-pound tycoon Dale J. Biederbeck III (Adam Arkin), a.k.a. "Dale The Whale." But Monk wonders how that can be possible - Biederbeck hasn't left his bed in eleven years, and can't even fit through his bedroom door!
