Book excerpt: It's a memorable year in Scotland. The country will vote on independence, Glasgow will welcome the world to the Commonwealth Games, and the world's best golfers battle it out in the Ryder Cup on Scottish soil. Meanwhile, Scots do what they always do - eat and drink too much, complain about the weather and, fortunately, have a laugh about it. Their tales of the funniest events will be sent to The Herald newspaper's iconic Diary column, and the best of them are gathered here.
