Season 3: Episode 20

Worried about turning forty, Carol exercies and diets with Karen. When Karen steps out, Carol sees a commercial for Skinny Tabs and orders them. She loses three pounds, but possesses so much energy that she drives everybody crazy and is constantly talking and working. Frank tells her that he loves her for who she is, not just her body. Al has to write a report on Abe Lincoln, but all the books on him are checked out. Cody takes her to Madame Sonya and he encounters Lincoln. Al does not believe and therefore, she does not see Abe, but she has a great idea for her report-- Abe in the 20th Century. Cody gives Abe's golf scorecard to Carol for her birthday.
