Billy Martin and George Steinbrenner
These two classic baseball characters, now both deceased, still loom large over the game, and their rocky professional relationship is the stuff of legends. Steinbrenner, the owner of the New York Yankees, fired and rehird manager Martin five different times. Somewhere in there, Martin coached the Yankees to the 1977 World Series title. Both of these individuals where defined by their tempers; you would not want to be that therapist.
