Run batted in or RBI is a statistic used in baseball and softball to credit a batter when the outcome of his at-bat results in a run being scored, except in certain situations such as when an error is made on the play. The first team to track RBI was the Buffalo Bisons.

Common nicknames for an RBI include "Ribby" and "Rib."

The plural of RBI is "RBIs". A common mistake is to conclude that the plural should be "RBI" because "runs" is the pluralized noun, but the entire acronym is properly pluralized.

The official rulebook of Major League Baseball states in Rule 10.04:

(b) The official scorer shall not credit a run batted in

The perceived significance of the RBI is displayed by the fact that it is one of the three categories that compose the triple crown. In addition, career RBI are often cited in debates over who should be elected to the Hall of Fame. However, critics, particularly within the field of sabermetrics, argue that RBI measures the quality of the lineup more than it does the player himself since an RBI can only be credited to a player if one or more batters preceding him in the batting order reached base (the exception to this being a solo home run, in which the batter is credited with driving himself in). This implies that better offensive teams—and therefore, the teams in which the most players get on base—tend to produce hitters with higher RBI totals than equivalent hitters on lesser-hitting team.

Damu the Fudgemunk (born Earl Davis on June 8, 1984, in Washington, DC) is an American hip hop music artist and producer from Washington, DC. In addition to his career as a solo artist, music producer, and DJ, he is a member of the groups Y Society and Panacea.

Damu released his official debut album as a member of Y Society, Travel at Your Own Pace, on October 10, 2007, to positive reviews. The album is reminiscent of true-school hip-hop with its liberal use of jazz and soul samples and scratching throughout. In 2008, Damu released two free albums primarily composed of instrumental music, titled Spare Time and Overtime. He built himself a respectable and loyal fan base through his unique YouTube videos and live street performances around Washington, DC, and New York City, which require him to use a portable electricity generator to power his sampler and speakers.

Damu the Fudgemunk releases the bulk of his music through Redefinition Records, a label that he co-owns and operates. The label focuses on releasing vinyl records and cassettes even if the records are also released on CDs.
