Maybe with another group of writers, it could have been funny. With the writers they had, though, every episode was a rerun of the forumula they developed in the pilot.
Straight man and girlfriend have romance.
Gay man inserts himself in SM&G's life.
SM begs GM to stop. GM delivers "life lesson" to SM's GF, while GM's boyfriend does his best impersonation of cardboard.
Sassy secretary delivers one sassy line.
GM's plot fails. SM saves the day. GM says thank you and vows to never do this again.
Rinse, repeat for next episode.
