QI is a BBC panel show that both educates and entertains. QI Masters Stephen Fry [Seasons 1-13] and Sandi Toksvig [Season 14+] ask questions that are very difficult and award points for answers that are either Quite Interesting or correct. However, points are deducted for answers commonly thought to be correct but are in fact quite wrong. Four Bantermeisters, including permanent panelist Alan Davies, try their best to separate the fact from the fiction.
