What's your favorite battle cry? From books, movies, cartoons, it doesn't matter. And why do you like it?

Perhaps not a true battle cry, but at the climatic scenes of the 1932 film, Island of Lost Souls, as the "Manimals" are stalking Dr. Moreau, they recite what Moreau had taught them: "What is The Law? Are we not men?....Law No More!"

Mine was from a D&D group back in the 80s.
"Are we having fun yet?"
"I've had fun. This isn't it.'
