Roger Price makes his only appearance in the series as Arrick, one of the scientists in the Control lab. Price was a writer and business partner of Leonard Stern, the executive producer of the series (and creator of the iconic credit sequence, in which Maxwell Smart walks down a corridor through an elaborate series of self-opening doors). Stern and Price were the co-creators of the word game "Mad Libs," and also Droodles - simple drawings that had amusing or surprising punch lines. To publish books of both creations he and Stern formed the publishing firm Price Stern Sloan.
