I wish the geniuses at the hospital here had thought of it instead of having this fresh-out-of-medschool doc try to do 3 layers of stitches on me once. By the time he managed to get to the second layer the anesthetic had worn off and he learned a new word every stitch he sewed in.
Hockey is Stanley Cup Champions, Football is Superbowl champions. I never did understand why the baseball championship was determined by the "World Series". So, you've got it right in baseball terms.
Maybe it's just commentators getting carried away. I've heard Superbowl winners being referred to as world champs numerous times, and I remember when the NJ Devils won the Stanley Cup they were called world champs on more than one occasion too.
Urban myth is that it was because when they started, they thought that all of the world would be interested in playing Baseball, and there were plans for a World series, however it never took off, and as a result they just left it as it is. Baseball was played in the UK around about the 1930's, and was gain popularity until the war, the proposed league in Britain never really got a chance to develop.
Hockey I think that World Champs is more reserved, becuase of the fact there's these stupid things called "Olympics", which determine who's the "world champ", then theres the World Juniors every year, and a bunch more. I think you've been drinking too much Guinness again Kev.
