Samantha Fights City Hall - S5-E9
Trivia: Because Erin Murphy, who played Tabitha, was ill, her fraternal twin sister Diane took her place in this episode. By this time, Erin and Diane didn't resemble each other as much as they once did, and it was obvious to regular viewers of the show that it wasn't the Tabitha they were used to seeing. The producers received several letters asking "Who was that?"
