If you look carefully at the very top of the screen during the scene where Olivia is telling the Huxtables that she didn't get to do her show-and-tell at school, you can see the microphone appear very briefly.
Pam calls Charmaine up her room saying "Come on up,
Charmaine," but when Charmaine knocks on the door, Pam
still has the dress she is working on in plain sight and
tells Charmaine to wait outside the door, while she hides
the dress and other sewing materials. Why did she tell
Charmaine to come up if she wasn't ready?
Lance: See you later, baby.
Charmaine: Lance, don't use outside words inside!
Pam: And did you know that Mr. Bostick is the ugliest man I've ever seen?!
Pam: Yeah, did you notice that there is hair coming from his ears and that ugly mole on his throat that moves up and down when he talks? Come on Charmaine, let's apply to college.... (Charmaine sits there stunned) DON'T HOLD ME BACK, CHARMAINE!
This is the second episode of the series in which none of the five Huxtable children appear.
Sabrina LeBeauf, Geoffrey Owens, Malcolm-Jamal Warner, Tempestt Bledsoe and Keshia Knight Pulliam do not appear in this episode.
Lance: Dr. Huxtable, I presume?
This is a reference to the H. M. Stanley quote, Dr. Livingstone, I presume?
