Abraham Rubin Hercules Benrubi (born October 4, 1969) is an American actor. He is known for his appearances as Jerry Markovic on the long-running medical television drama ER, for his first role as Larry Kubiac on the series Parker Lewis Can't Lose, Dennis in Without a Paddle, and for his voice acting on the Adult Swim claymation series Robot Chicken as well as numerous video games including many in the World of Warcraft series.

Benrubi was born on October 4, 1969, in Indianapolis, Indiana, the eldest son of Patricia and Asher Benrubi, who was a rock singer and has been a radio personality^[1] known as "The Smash" to St. Louis radio audiences.^[2] His paternal grandfather was from a Greek-Jewish family. His paternal grandmother, who was born to a Greek Orthodox Christian family, helped shelter Jews in Greece during World War II and later converted to Judaism.^[3][4]

Benrubi graduated from Broad Ripple High School in Indianapolis, the same high school alma mater of talk show host David Letterman, and professional sports figures Mike Woodson and Rosevelt Colvin.

Benrubi's first major role was on the show Wings, as Roy "R.J." Biggins, Jr., Roy's gay son. He would appear as R.J. twice: once during the show's second season, and again during the seventh season, shortly after he began working on NBC's ER.

Between the first and second seasons of Parker Lewis Can't Lose, Benrubi and co-star Taj Johnson worked as roadies for No Doubt's first tour.^{[dubious – discuss]}

Benrubi appeared on ER from its first season, playing desk clerk Jerry Markovic. He was a regular cast member from 1994 to 1999; again from 2002 to 2006; and again from 2008 to 2009.

Benrubi starred as one of the main characters in ABC's show Men in Trees (2006 to 2008), playing bartender/millionaire Ben Tomasson. This was a role where he got noticeably more main dialog and depth than with his previous longtime characters on ER and Parker Lewis Can't Lose, where he played a more supporting role. Ben Tomasson was described as "the cuddliest TV character since Jorge Garcia's Hurley on Lost" by TV-critic David Bianculli.^[5]

Following the cancellation of Men In Trees in early 2007, Benrubi returned to the cast of ER in late 2008 for the show's final season.

Benrubi portrayed a young Dan Conner, the character portrayed by John Goodman, in a flashback episode of Roseanne.^[6]

Benrubi starred in the short-lived ABC show, Happy Town (april to June 2010) where he portrayed the part of Big Dave Duncan. Almost immediately after ABC announced the series' cancellation, he appeared in a new show Memphis Beat, where he portrayed the part of police Sgt. Jody "JC" Lightfoot, a desk sergeant who is 1/16 Chickasaw by a distant relative, but chooses to embrace Native American culture all the same.^[7]

In May 2011, it was announced that he would star in Glutton, a "3D psychological thriller" directed by David Arquette. Benrubi would have played Jethro, a 1,200-pound man, forced to save his sister's life.^[8] Jethro's sister would have been portrayed by Patricia Arquette, while Kacey Barnfield would have also starred as his blind neighbor and only friend.

Benrubi is a member of Los Angeles' Sacred Fools Theater Company.^[9]

Other work includes portraying Mose in the 2003 western Open Range, a role the actor won because he had been cut out of director Kevin Costner's previous film, The Postman. He frequently voices characters on Adult Swim's stop-motion animation show Robot Chicken (created by personal friend Seth Green), and has also contributed to a second show from Chicken's creators, Titan Maximum.
