Stephen Merchant and Newcastle are right: the 4th of July is basically a celebration of a breakup that happened 300 years ago.
"Do you really still have to celebrate your emancipation from us?" Stephen asks. "That's like your girlfriend breaking up with you and then celebrating with fireworks. Every year. For 300 years."
Stephen goes on to say how great America would be if the Brits were still in charge.
"Great Britain 2" would be the greatest country on earth, dammit.
