(1) Viz magazine
(2) The McMunchies sandwich bar and Mary Blair, its proprietor
(3) The skyline of Aberdeen with an arrow above pointing down
(4) Martin Clunes (from the BBC TV sitcom "Men Behaving Badly")
Well, Greg guessed it - the odd one out is Martin Clunes. Clunes is suing Bernard Ingham for libel for calling him (in his column in a tabloid newspaper) "a foul-mouthed yob". All the other three relate to litigation to do with McDonald's.
As a finale to the item, Angus Deayton (the panel game host) read out the Viz originial of the laundry/Oxfam top tip, followed by the McDonald's version used in a recent ad campaign - they are almost identical. Angus then quoted a McD's spokesperson - basically he made a joke about how their explanation for the 'apparent' plagarism was clearly all a load of bullshit.
