She had some pretty good quotes.
"Circular logic will only make you dizzy, Doctor!" (Also in my sig.)
(To the Doctor) "Maybe you should see a doctor?"
"I never saw anyone love himself so much for less reason."
The Master: I AM THE MASTER!
Peri: So what? My name is Perpigilliam Brown and I can shout just as loud as you can!
I did like her better with the Fifth Doctor, though. He brought out the sweeter elements of her nature, while she never really trusted the Sixth Doctor after the whole regeneration fiasco.
EDIT: But, I guess I am a lesbian, so maybe I got the wool pulled over my eyes by her boobs as well.
