American teams calling themselves world champions...

Let me tell you, this irritates me the most of all in American sports. When you win a game that is only played in America, you can't call yourselves "World Champions." And the "World Series" is played in the US (and once every 20 years in Toronto.)
Especially in basketball, which is played in Europe and Asia (mostly) as well, you can't call yourselves world champs. Especially when you refuse to play European clubs in real competition.
