227 - Season 3 Episode 24 Best Friends

When Mary's high school friend comes to visit, everyone is excited to meet her because she is a famous writer, psychologist, and romance adviser (like Dr. Ruth). Mary imagines what it would be like to be that famous and well liked. She begins to get jealous when Brenda tells her that she wants to be like Dr. Butler. She tells Lester how she feels and he admits that he thinks Thelma may be jealous of Mary and her stable life. Mary and Thelma get in an argument about who is jealous of whom and they bring up a lot of things that happened in the past. They wind up laughing about how silly they were acting and make up.
