Incredible but true: While attending college, Mayberry schoolteacher Helen Crump was arraigned on a felony charge! Andy tries to cover up this skeleton in the closet, but since it was he who dug up the story in the first place, he manages only to make things worse. To save her job, Helen has to tell all to the school board-and her explanation makes a lot more sense than anyone would have previously suspected. Written by Doug Tibbles, "Helen's Past" first aired on February 19, 1968. ~ Hal Erickson, All Movie Guide
