My only exposure to Medieval Times — a national entertainment chain featuring jousts, sword fights and 11th century fare — was the solitary time my husband forced me to watch that ridiculous movie, “The Cable Guy.” Jim Carrey’s character is absolutely obsessed with the dinner theater venue, and he drags his would-be best friend, played by Matthew Broderick, to the show. There, Broderick encounters the key quirk of the place: they don’t provide silverware with the meal.
