Comedy preview: Henning Wehn, London

For the likes of Stan Boardman (he of the "menaced by a bunch of Fokkers" routine that memorably disfigured TV back in the 1980s), the idea of a "German comedian" would be the set-up for yet another rib-ticklingly xenophobic joke. Hagen-born Henning Wehn is aware of the prejudices about his country - that the people are humourless, pedantic, and ruthlessly efficient - but the amiable, self-deprecating and witty way in which he exploits those stereotypes throws a gentle light on the boorishness and jingoism that are part of the British psyche. His response to the English football chant of "One world cup and two world wars", answered with "Three World Cups and one world Pope" is typical, using blunt logic to show up the nonsense of narrow-mindedness. And he's a dab hand with a one-liner.
