M&M Boys
The "M&M Boys" were the duo of New York Yankees baseball players Mickey Mantle and Roger Maris, who were teammates from 1960 to 1966. They gained prominence during the 1961 season, when Maris and Mantle, batting third and cleanup (fourth) in the Yankee lineup respectively, both challenged Babe Ruth's 34-year-old single-season record of 60 home runs.
