Joining John Lloyd and Jo Brand in the museum this week are comedian Lucy Porter, etymologist Mark Forsyth and advertising guru Dave Trott.

Lucy Porter, comedian, ex-journalist for The Big Issue, and the record holder for the highest score on Celebrity Mastermind (35 with the specialist subject of Steve Martin), donates to the Museum the material Lycra, which Lucy claims is not treated with the respect we should. Lycra can stretch up to five times greater than its original length.

Mark Forsyth, an copyeditor and etymologist who has written such books as The Etymologicon and a blog called The Inky Fool, offers up a printer - that doesn't work. This is in reference to the word "wayzgoose", meaning a day when a printer doesn't work, so it is a printer's holiday.

Dave Trott, a veteran of the advertising world whose first job was creating the advert for "lipsmackin' thirstquenchin' acetastin' motivatin' goodbuzzin' cooltalkin' highwalkin' fastlivin' evergivin' coolfizzin'" Pepsi, gives a ploughman's lunch to the Museum. People think it is much older than it is, but actually it was invented in 1960 by the British Cheese Board to sell cheddar.
