You're in for a real treat this week as Pointless hosts Alexander Armstrong and Richard Osman hurl themselves into this sitcom playing themselves.

Daisy (Katy Wix) has been accepted as a contestant on the show and Lee uses nefarious means to convince both her and Lucy that he is some kind of quizzing superstar.

It's a glorious set-up as Daisy and Lee prepare to display their entire lack of general knowledge to the nation at large.

For once, it's not just Lee himself who hogs all the best lines. Wix as the clueless Daisy is absolutely terrific, whether she's trying to name an American president or blatantly stalking Osman on whom she has a massive schoolgirl crush.

As for Osman, playing yourself isn't as easy as you'd think, but he proves yet again that there's not much he can't turn his hand to - even if he does have to duck to get through the doorway to his own dressing-room.

It's an episode destined to become as enduring a comedy classic as The Young Ones' appearance on University Challenge.
