Pointless, the BBC One quiz show, is an afternoon viewing pleasure for many. Hosted by the always affable Alexander Armstrong, with help from the witty Richard Osman, the show sees contestants trying to think of forgotten facts and score the fewest points.

Little known knowledge is the key to success on Pointless. Each question posed has already been asked to a panel of 100 people before the show to determine the most obvious and the most obscure answers.

For example, if you had to name British comedy double-acts on Pointless you wouldn't get many points for Morecambe & Wise but would no doubt score well if you managed to remember an act like Naughton & Gold (music hall comedians from the early 1900s).

Pointless has recently expanded out into a Saturday night celebrity edition, and a forthcoming show is likely to be of particular interest to comedy fans...

On the 2nd March Alexander Armstrong and Richard Osman will bring their humour to a Comic Relief special of Pointless Celebrities (incidentally, did they know what they were doing when they called the spin-off that?). Pairs of comedians will take part in the special show, with all the cash earned going to Comic Relief. Here's a look at the teams:

Stand-up Andi Osho and comic actor David Schneider:

Fast Show duo Charlie Higson and Paul Whitehouse:

Red Dwarf star Danny John-Jules, and Ben Miller, the host's double-act partner:

Stand-up comics Ed Byrne and Shappi Khorsandi:

The Pointless Comic Relief special will air on BBC One at 6pm on 2nd March 2013.
