Get ready to feel more than a little emotional as Stephen Fry says “gooooood evening, good evening, good evening, good evening” for the last time.

The moment has finally come for the QI host to leave the show, following 13 years and over 180 episodes of fiendishly difficult and brilliant funny brain teasers.

Fry’s swansong episode airs on Friday 19, with the host joined by Sara Cox, Bake Off’s Sue Perkins, and Chris Addison for one last round of General Ignorance.

Before he goes, take a look at some of Fry’s best moments through the years – from his tongue-twisting rapid-fire run-off of Scotch inventions, to the time he caused an explosion of ping pong balls in the studio, and the moment a bodged introduction resulted in an impromptu sing-a-long.

While Fry will undoubtedly be missed, a brilliant replacement is on the way – the next series will see Sandi Toksvig, veteran of Radio 4’s quick-witted and topical News Quiz, take on hosting duties.
