It's an old gag really, but if it helps to add to the "Britishness debate" that Gordon is so desperate to have then the following should help anyone understand what being British mean.
Being British is about driving a German car to an Irish pub for a Belgian beer, then when travelling home, grabbing an Indian curry or a Turkish kebab. Then when you get home sitting in a Swedish chair to watch American T.V shows on a Japanese television.
Only in Britain can a pizza get to your house quicker than an ambulance. Only in Britain do Supermarkets make sick people walk all the way to the back of the store to get their prescriptions, whilst healthy people can buy cigarettes at the front of the store. Only in Britain do banks leave both doors open and chain the pens to the counters.
Only in Britain do we leave cars worth thousands of pounds on the drive and lock our junk and a cheap lawn mower in the garage. Only in Britain do we have disabled parking spaces in the car park of a Skating Rink.
