* EarWorm: The Final Frontier, by Paul Reiser & Don Was. Originally performed by [[http://www.youtube.com/watch?v=OvBZ4KjfSWE Andrew Gold]], redone for the final two seasons by [[http://www.youtube.com/watch?v=YaIKpzsBVgE Anita Baker]]
* EnsembleDarkhorse: Murray the dog, as noted above. It says something that Academy Award winning actress Helen Hunt was frequently outperformed by a dog.
* TheyJustDidntCare: In one episode, Paul's parents are in a production of ''ThePiratesOfPenzance.'' Except for having pirates and "The Major General's Song" in it, it's ''nothing'' like the actual operetta. No one in the building had ever done ''Pirates?''
** It was stated that the cast started making changes to the script and it got so bad that Paul (who was directing) just gave up and let them do what they wanted.
