FDR: Oh, I'm sorry, was wiping out our entire Pacific fleet supposed to intimidate us? We have nothing to fear but fear itself, and right now we're coming to kick your ass with brand new destroyers riveted by waitresses. How's that going to feel?
CHURCHILL: Yeah, you keep bombing us. We'll be in the pub, flipping you off. I'm slapping Rolls-Royce engines into untested flying coffins to knock you out of the skies, and then I'm sending angry Welshmen to burn your country from the Rhine to the Polish border.
US. NOW: BE AFRAID!! Oh God, the Brown Bad people could strike any moment! They could strike ... NOW!! AHHHH. Okay, how about .. NOW!! AAGAGAHAHAHHAG! Quick, do whatever we tell you, and believe whatever we tell you, or YOU WILL BE KILLED BY BROWN PEOPLE!! PUT DOWN THAT SIPPY CUP!!
