This is a pocket-sized glimpse into the world of the US president's beloved communications system, without which he is rarely seen and about which the world's press has already devoted numerous column inches. From ex-president GW Bush ('43') asking about lost property, to playing hide and seek with his secret service protection ('Dammit. U guys r good'), to hilarious correspondence with the likes of Tony Blair, the Kasper Hauser comedy group has filtered out the very best of the commander in chief's correspondence for your amusement.
