And Baby Makes Three (3x4)

Air date: Oct 24, 1987

When Mary is concerned at Calvin and Brenda's nonchalance about teenage pregnancy, she designs an experiment with their sex education class where the kids must take care of an animal. Brenda and Calvin ""adopt"" a piglet named Alberta and she is a handful. All of the kids in the class realize how hard it is to take care of animals, let alone a baby.
