Well I think he had some good peices of dialog in B/W.
So what your favorite quote from him?
For me its "Burn baby burn!!" I found that quite funny.
I like the quote of his: "They're not here. Let's ride the Ferris wheel and see if we can spot them. I love Ferris wheels… The circular motion… The mechanics… They're like collections of elegant formulas."
"I am the king of Team Plasma"
SURPRISE! WE NEVER THOUGH THAT WAS COMING
I love EVERY quote that N says. ANYTHING he says is so... Wonderful.
"I've been living with Pokemon ever since I was born, so it's easier for me to talk to them than with people. Because Pokemon never tell lies."
-my social life in a nutshell and how I feel about real animals
"Burn, baby, burn!"
N + Reshiram = Awesome! Too bad that means you get Zekrom, though...
