Don't tell em Pike

Well, its a bloody good job that the Germans didn't have rubber dingys in 1940 isn't it.

Peter Benchley, come back all is forgiven, we need Jaws in the English Channel :)

Or why not take to sea in boats and play a marine version or 'Rollerball' with the invaders. Put up the Jolly Rodger at the last minute. Have your pirate ship with a figurhead of a female politician (quite a few are so ugly it will scare the fuckers back to frogland). Play 'frigging on the rigging' at top volume,, then board their dingys. Make em walk the plank.
