Andrew Brown, the Advertising Association's director-general, has had his briefcase nicked and with it a briefing paper he was about to present to the IPA. Very embarrassing for one of the figures making the industry's case in the obesity debate. But not half as embarrassing as the scene of the crime: a McDonald's where Brown was having a quick burger ... Hamish Pringle, Brown's IPA counterpart, is similarly red-faced. Speaking to students at a conference last week, Pringle wanted to show how easy it is to post a CV on IPA Jobs Online. Alas, he forgot that posting a CV in this way automatically precipitates an alert e-mail to all companies registered to receive them ... BBC Magazines resorted to desperate measures to spice up a dull evening talking ABC figures. The theme was speed dating which allowed everyone in the room to spend three minutes with everyone else. No wonder the guests didn't all leave for the Maxim and Marie Claire parties ... News that John Banks is about to step down from the leadership of FCB London has got the Diary wondering if he was the inspiration for Erasmus Banks, a Washington lawyer who appears in The Final Act, a potboiler written by the WWAV Rapp Collins founder John Watson. The name of his fictitious Washington law firm? Hoggins Banks O'Shea.
