Coach Penny is cranky. She hates Jessie ever since she she wrote "Best Year Of My Life," because Jessie wrote a song about her perfect boyfriends, which makes the single gals feel bad. She also hates Harold, her ex-fiance who dumped her one month before their wedding and started dating the lunch-lady. She's so strict, that even her daughter, Madge, calls her "Sir!". She is very energetic.
