Miss DeGroot was the mean-spirited librarian who worked at the library Al Bundy used to frequent as a child, who appeared in the Season 3 episode of Married... with Children titled "He Thought He Could". She was noted for using an unusually large amount of sugar in her tea, and her intense hatred of Al, which upon her own admittance was unusual due to the fact he was a mere child at the time. Her hatred of Al, and desire to get him in the end, caused her to continue to work at the library for years afterward, waiting for the day when she finally got her revenge. When Al was a child, he always insulted her for being fat. Miss DeGroot was played by veteran comedic actress Lu Leonard, who appeared in numerous Three Stooges shorts during the 1940's and 1950's.
