There I was on my bike in the third lane of the motorway (if you have never driven on a British motorway, they are very hostile places). I was doing around 90mph and everything suddenly went wobbly. A rear tyre puncture, great, super, fanbleedingtastic, just what I needed. I eased onto the hard shoulder, threading between tailgating lorries in the process. I surveyed the situation, reached for my mobile phone. My arms weren't long enough; it's on the worktop in the kitchen 45 miles away. Within a minute another biker stopped to offer help (thanks mate, bikers are good people). I managed to limp the 2 miles to the local tyre dealer at 10mph, that was the real scary part and now have to scrub in a new tyre on the way home which is also rather scary.
