It's "No Diet Day" (yay!) so get your teeth into a massive smoked wiener or, if that's not enough for you, a sausage that stretched for 63 km or 39 miles; strip off for the largest nude photo-shoot then head off on a charity walk with over 700,000 other people (or alone, with your fridge). Finally have a well-earned snooze on the world's biggest mattress.
