DAVID MAMET'S Oleanna caused more arguments at dinner parties than any West End play for years. Few couples broke up after an evening watching, say, Jeffrey Archer's Beyond Reasonable Doubt (unless one half wanted to know why the other had bought the tickets in the first place). But if the rumours are true, Mamet's slippery take on the sex war has single-handedly doubled the divorce rate. And even though it's been claimed that the men who shouted 'Kill the bitch' on the first night were plants, Oleanna clearly had a profound effect on its audience. This was at least partly due to the acclaimed original cast; but new leads Denis Lawson and Michelle Fairley have brought fresh impetus to the piece. Now you can test your relationship by buying two tickets for the price of one: simply ring the Duke of York's on 071-836 5122 and give the correct answer to these two questions. Isabel Lloyd
