While talking to Dick about older TV shows, Michael mentions that show with "the shrink that stutters". Dick responds with "stammers". This is in reference to The Bob Newhart Show.
There was also an episode of "The Bob Newhart Show" (Season 6, Ep 20) named "Carol Ankles for Indie-Prod". The term 'ankles' is used here to "reveal a small part of your intentions in order to attract support without actually committing yourself to do anything."
