Step into Oscar's Barbershop for another hilarious season of "That's My Mama," one of the '70s funniest hits. There have been some changes- Earl's quit the post office to take up cutting hair, Junior's in college( yes, college) and oddball neighbor Laura (Helen Martin of TV's "227") is along for the ride. But Mama's still Mama, and she's still in charge. Whether it's settling fights or keeping an eye on the money, Mama's the one to count on in this family. Starring Clifton Davis (TV's "Amen") and Ted Lange("The Love Boat's" Isaac), this season of the show includes episodes from the creative minds of TV's "M*A*S*H" and "Barney Miller"
