I also worked with a bloke called Joseph King and my wife had a best friend called Jovanka, which was prounounced Yovanka. This of course made it worse, or better dependant on your point of view. Better for me, cos everytime I saw her I would say her name quite aggressively.
My wife also had an old school friend called Yura Thikee.
I did also work with a bloke called Colin Shufflebottom. He insisted it was Colin Shufflebotham! And I'm sure a lot of the older posters on here will remember a hairdressers in the city centre called Mike Hunt.
