'Goodwill' visit by HMS Bulwark to Hamburg ca. 1967. Scene, a bar with a small dance floor under a spotlight, tables ranged around. Enter Jack. Throws his hat into the spot and asks 'Right, which of you Jew-burning bastards is going to buy me a beer?' Source - the Officer of the Patrol from Bulwark who had to stage the subsequent rescue. Seems (surprise!) the locals did not have well-developed sense of humour.
