What's the best nickname in baseball?

I love a good nickname, and MLB's got lots: The Wizard, Teddy Ballgame, Stan 'The Man', The Iron Horse, Sandman....

Who's got the best bickname in your team's history? Who's got the best nickname ever?

(Frank Thomas gets my vote. Personally, I think 'The Big Hurt' is the best nickname in all of sports.)
