Quote from Stuart in the episode Spoiler: We're as Confused as You Are
Stuart: Your Honors, if you'll indulge me, I think I can clear this up. General Adams: Make it quick. Stuart: We're not from your universe. These two gentlemen and I are from a version of reality that's even worse than this one. [Penny sighs and places down her folder] There's, uh, mutants and giant moths. You don't even wanna know. And this lovely young woman is from a universe where humanity is controlled by a globe-straddling artificial intelligence. Denise: Not helping. Stuart: So, what you're calling desertion, cowardice in the face of the enemy, is actually us trying to bravely restore order across all universes. [the judges are silent] [Penny shakes her head] Yeah, just shoot us. [sits down] Kripke: Hey, that was gweat. Weawy gweat.
