I have an idea! Scary I know but bare with me. Now the American is no more! It would be great for the grand tour to do a proper farewell sketch, with the American turning up in the distance outside their permanent tent on a horse, clasping to an American flag and sword, ready to do a full on charge towards the trio troopers, but it goes horribly wrong! First of all the horse decides to take a dump and then a wee and finally he gets bucked off which sends him flying into a monster cowpat! Looking very embarrassed and angry he then walks off into the distance unknowingly walking over an unexploded world war two bomb, which effectively sends the American hurtling into outer space and beyond, and on that bomb shell, good night!
