Sketches often start pleasantly enough, before veering off in a wholly unforeseen - and usually rather nasty - direction. Shocks are their stock- in-trade. Imagine Joe Orton re-written by David Lynch and you're some way there. An innocent-looking skit about a monotonous cave-guide, for instance, soon evolves into an emotional confession of his guilt about a young boy who died there. Another harmless-seeming routine set in a joke-shop degenerates into a sadistic discussion about the joys of hot sweets which contain tongue-burning potassium.
Most unusually on a circuit jam-packed with stand-ups desperate to be loved, the League of Gentlemen are not afraid to deal with such harsh, potentially alienating subjects as child abuse, murder and bullying. The first sketch show to win the Perrier since 1985, they manage the unlikely feat of making these topics humorous through a winning combination of sharp writing and even sharper performing (all three are trained actors).
You may not feel comfortable in the company of the League of Gentlemen, but you certainly won't be bored.
