It's Not What You Know is a comedy panel show hosted by Joe Lycett (previously Miles Jupp) in which it's not what you know, but who you know that matters... and indeed, how well you know them.

It's a bit like Mr & Mrs, except that it's not played by husbands and wives. Instead panellists can pick anyone they like to be their partner/nominee: dad, cousin, best friend, mother-in-law. It just has to be someone they're close to.

Three panellists are asked to guess how their nominees answered certain questions. Things like "what's your motto in life?" and "What did X give you last Christmas?" If the panellists match their nominees' answers they get points.

Some episodes also feature a special guest contributor whose answers the panel must also try to predict.
