Former NFL All-Pro, actor, and reclining-chair spokesman Karras and his screenwriting collaborator gently send up football, television, and Karras's old cohorts from his Monday Night Football broadcasting incarnation. No football knowledge is needed to enjoy this bit of nonsense about an irresistibly nice accordion player who is drafted into service as a commentator for network football broadcasts. Some knowledge is expected, however, of the excesses of television and of the reputations of ABC's real-life Monday Night Football team during Karras's enlistment. The amiable accordionist in this amusing story is Lazlo Horvath, only child of expatriate Hungarian circus stars, whose boyhood was spent absorbing televised commercials for playback in later years. The squeeze-box and boob- tube skills have paid off in Horvath's career as a motel and casino entertainer. And those same skills have come to the attention of staggeringly rich conglomerateur Pineas Higgins, who thinks that Lazlo is the only person who can pump life into the sagging ratings of the Tuesday night football broadcasts that Higgins sponsors. Lazlo, who never says no, is accordingly flown to Chicago, where he joins verbose, bewigged Haywood Grueller and irresistibly priapic Lance Allgood, his new partners in broadcasting. Grueller, Allgood, and Yanya, the show's gorgeous and stupendously capable producer, try like crazy to bottle up Lazlo, who plans to use his air time singing jingles, but Grueller's ex-wife, disguised as Julia Child, sabotages the game and Lazlo must save the day. Nobody gets hurt, except for a loathsome little producer; everybody has fun; and the silliness ends before it can get tiresome.
