From Bender's Big Score:
"You're wrong! Fry is dead! I killed him!
Amy: Bender, why?
Personally, I blame you!
Amy: But how can you?
Well, it ain't easy, but that just proves how great I am.
Not 100% accurate, but that's the gist of it. Just to be sure, the unmarked quotes are Bender's
Bender: Struggling against all odds, I, Bender, managed to kill him.
Amy: Aw, don't blame yourself bender.
Bender: I don't. I blame all of you.
Amy: Us!? How can you blame all of us?
Bender: It wasn't easy. It just proves how great I am.
