Denise's dorm room and roommate are different than in "A Different World."
This episode is setting up the spin-off show "A Different World."
There is no studio audience for the entire second half of this episode.
Ted Ross (Professor/Dr Harris) is only 3 years older than Bill Cosby, which is too young to even be a professor, much less Dr (PhD) teaching Cliff.
Phyllis Yvonne Stickney, who plays Denise's roommate Phyllis, will appear in a few episodes of the first season of "A Different World" as this same character. However, Stickney's role was never more than a bit character playing one of Gilbert Hall's many residents.
