Today's panellists are Irish comedian Ed Byrne, Tasmanian stand-up and art expert Hannah Gadsby, punmaster general Milton Jones and classics boffin Natalie Haynes.

Today's Letter of the week is 'N'. Ed Byrne explains what the phrase 'nuking the fridge' means and Hannah Gadsby deduces what the Sicilian phrase 'go to Naples' means.

In a round about derogatory terms Natalie Haynes is asked what a 'fishbagger' was in the late nineteenth century and Milton Jones is asked what the American term 'ballclankers' from the 1960s might have meant.

The panellists also attempt to ban their least favourite words including 'blog', 'Christmas', 'fablet' and 'simples'.

And finally they try to unearth the meaning of some words found in a dictionary of thieves' slang from 1673.
