Donald Harris and Ronald Harris (born October 23, 1960) are American twin brothers best known for their professional wrestling careers with promotions including Extreme Championship Wrestling (ECW), World Championship Wrestling (WCW), and the World Wrestling Federation (WWF, now WWE). They are now co-presidents of the Nashville-based Aro Lucha professional wrestling promotion.

For the majority of their careers, the brothers performed as a tag team. They wrestled under their birth names and a variety of ring names, including Don Bruise and Ron Bruise (the Bruise Brothers); Eli Blu and Jacob Blu (the Blu Twins); Jared Grimm and Jason Grimm (the Grimm Twins); Skull and 8 Ball (the Disciples of Apocalypse); and Patrick and Gerald (Creative Control).

Don and Ron Harris were born in Florida. In the 1980s, Ron and Don relocated to Nashville, Tennessee, in order to become professional wrestlers. Ron worked as a police officer in West Palm Beach, Florida, prior to moving to Tennessee with his brother.

Don and Ron Harris, with support from the country music group Sawyer Brown, debuted in the Continental Wrestling Association in December 1987 as "The Bruise Brothers", where they became two-time World Tag Team Champions. When the CWA became the United States Wrestling Association in 1989, the Bruise Brothers remained in the promotion. Don and Ron won five more Tag Team Championships, with Don winning two additional USWA World Tag Team Championships with Brian Lee and Ron winning an additional USWA World Tag Team Championship with Jimmy Harris (no relation) as "Beauty and The Beast". The Harris Brothers made a final appearance with the USWA in 1996 as "The Grimm Brothers".

In 1991, the Bruise Brothers debuted in the Oregon-based National Wrestling Alliance Pacific Northwest promotion, where they became six-time Tag Team Champions. Don Harris was also part of the last match in that promotion's television show, defeating Jon Rambo. On January 27, 1992, the Harris Twins received a tryout match with the WWF at a Wrestling Challenge taping in Lubbock, Texas, defeating Khris Germany and Todd Overbow. They beat the duo again the next night in Amarillo. In March 1993, the Twins worked a few matches for World Championship Wrestling.

In 1993, the Harris Brothers joined Smoky Mountain Wrestling as the Bruise Brothers, managed by Jim Cornette. On June 28, Cornette led them to a victory over the Rock 'n' Roll Express, Ricky Morton and Robert Gibson, for the SMW Tag Team Championships. The Bruise Brothers remained in SMW until early 1994, participating in hardcore matches such as Street Fights and steel cage matches.

The Bruise Brothers appeared in Extreme Championship Wrestling in 1994. On February 5, the ECW Tag Team Championships were held-up after a controversial ending to a match between the Bruise Brothers and the incumbents, The Public Enemy. The Bruise Brothers went on to participate in some of the first ECW hardcore matches, and feuded with Shane Douglas.

The Harris Brothers were signed by the World Wrestling Federation (WWF) in January 1995, where they were renamed "The Blu Brothers", Eli (Ron) and Jacob (Don). They retained their trademark bushy beards and long hair and donned garb to resemble mountain men, and were managed by Uncle Zebekiah. They made their WWF debuts shortly before the 1995 Royal Rumble and were defeated by Lex Luger and The British Bulldog in the opening match of WrestleMania XI. Jacob Blu competed in the King of the Ring 1995 tournament losing to Razor Ramon in the qualifying round. Following a series of losses to the Smoking Gunns, the Harris Brothers left the WWF in October 1995.
