"QI" is a quite interesting quiz show in that correct answers are not necessarily the goal. But responding to presenter Sandi Toksvig's mostly obscure questions in a funny or interesting way, regardless of whether the response includes a right answer, is what scores points. And points are deducted if answers merely repeat common misconceptions and urban myth. It's OK to be wrong, but don't be obviously, boringly wrong. Toksvig welcomes to each episode a four-person panel made up of comedians, writers and broadcasters, plus permanent guest Alan Davies.
