I workin Holand for a Dutch company. I am Welsh. I have a colleague who lives in London and is English. Needless to say we are at each other, especially during rugby season. All in good fun ofcourse. So one day he made this remark about us Welsh. So I decided to take action. I created an OU especially for him and set a few policies. The best one was that whenever he wanted to log on he had to press ctrl+alt+delete he would get a popup saying: "Wales rules, England really sucks. If you agree to this statement, please click OK". There was no other option for him than to click OK or else he just couldn't log on. I promised him I would get rid of that message if he wore something Welsh to a rugby match. He has a few Welsh friends who are still laughing. This was just one of the things he had to endure.
Ofcourse he is a really cool guy and we still join eachother for a few pints now and then
