Dick takes Mary up to his penthouse and wines and dines her, but she tells him that she doesn't believe in true love anymore, no matter how hard he might try to persuade her otherwise. Meanwhile, Sally isn't happy being second fiddle to Don's wife so she asks him to break up with her. Don, however, wants to run for president and so refuses, so Sally breaks up with him; while at NBC, Tommy's huge ego and demand for a high pay on Saturday Night Live leads Harry to fire him.
