I hesitate to start this one because of how the previous discussion of the Washington area football team's name ended, but I thought this was interesting - Mike Carey, the NFL ref, asked and was allowed to not referee Washington games because of the team name. Don't think I've ever heard of refs asking to avoid refereeing a particular team's games before.
