This is one of my favorite quotes because it shows Peter's inattentiveness:

Chris: Not very good. I don't think Mrs. Lockhart likes me at all.
Lois: Mrs. Lockhart?! Your teacher?
Peter: Whoa, whoa, whoa, whoa, whoa, whoa, whoa, whoa, whoa, whoa, whoa, whoa. Lois, this isn't my Batman glass.

And then there's one right after that where Stewie's eye turns red and he's like, "Aagh! Broke a damn blood vessel!"
