Most of us face petty frustrations like post office queues, parking tickets and automated phone lines. Most of us just grin and bear it - but not Bob Howard and Bob Johnstone. They've taken action. They send ludicrous invoices to anyone and everyone they think deserves them. The responses they receive - from Ikea and Southern Railway to the Archbishop of Canterbury - range from the incredulous and bemused to the good humoured and witty. Initially, the two Bobs started invoicing people just to make themselves laugh - but soon realised it was too funny to be kept to themselves. For anyone who's ever threatened revenge against life's little annoyances, but done nothing about it, The Invoice Book points the way. Ridiculous, hilarious and on one occasion even successful, Bob and Bob's invoices are the funniest pieces of nonsense you'll read all year.
