10. I think Herbie's answer is wrong for this one (unlikely as that seems). Bill Cosby does make an appearance in B&C&T&A, though if you blink you miss it. It's in the night club. I'm guessing the correct answer is D (only because I'll bet there has never been a Calvin Brown Look-Alike Contest).
I'll try matching quotes with episodes:
15.
A. Casanova from Canarsie
B. Dragon's Teeth
C. No Exchange on Damaged Merchandise
D. To Florence with Love
E. Mainly on the Plains
