Anyone seen Whoops Apocalypse (1986)? Peter Cook plays a prime minister who leads Britain into a meaningless war to defend a far-flung territory that no-one's ever heard of and in doing so plunges the world into nuclear Armageddon. Grim synopsis, but god, it's funny! My favourite scene is the bit where terrorists have spiked his bath with industrial-strength acid which liquifies his hand when he dips it in to test the temperature of the water. There is an ominous bubbling sound and then it cuts to him in hospital with a hook on the end of his arm saying "British surgery is the finest in the world!"
