Henning is The German Comedy Ambassador in The United Kingdom. This is not the easiest of jobs because the Germans allegedly do not have a sense of humour. Henning does not find that funny.
After his last show tackled those well-known staples of light entertainment that are the British obsession with home ownership and the self-serving nature of most fundraising efforts, this time Henning's having an unbiased look at immigration. He also wonders, if, generally speaking, people are competent. Luckily in his case this doesn't matter as either he's funny or he lives up to a national stereotype. It's a win-win situation.
