I'm sure you guys have probably seen this online but I found it recently on an American site, I changed the wording slightly to sound more British (no offence to any Americans from this site!) and its my favourite thing to quote when my friends take the mick!!

"You don't have to be a cowboy to wear a cowboy hat.
You don't have to be an athlete to wear a tracksuit.
You don't have to be a pilot to wear a bomber jacket.
You don't have to be a baseball player to wear a baseball cap.
You don't have to be a soldier to wear camouflage clothing.
You don't have to be a man to wear trousers and....
You don't have to be a Scot to wear a kilt!"

I think thats great
