‘Kingpin’

Its heroes are none too smart, and their story is riddled with improbabilities, sentimentality and silliness. But “Kingpin’s” co-directing brothers Peter and Bobby Farelly are funny, canny filmmakers. Woody Harrelson (left) and Randy Quaid (right) are a constant joy. Harrelson’s Roy Munson was the state bowling champion of Iowa, a gutsy small-town guy who took his fashion tips from “Saturday Night Fever” and was headed for national champ when he was sidelined (SHOW Sunday at 4:30 p.m.; and Thursday at 8 p.m.).
