Dream 6: Middle Weight Grandprix 2008 Final Round was a mixed martial arts event promoted by Fighting and Entertainment Group's mixed martial arts promotion Dream on September 23, 2008.
 The event hosted the crowning of Dream's first Middleweight Champion, Gegard Mousasi, after the conclusion of the Middleweight Grand Prix.
Gegard Mousasi (born 1 August 1985), is a Dutch mixed martial artist and former kickboxer currently competing in Bellator MMA.
 He is the former DREAM Light Heavyweight Champion, former DREAM Middleweight Champion, former Cage Warriors World Middleweight Champion and the former Strikeforce Light Heavyweight Champion, thus making Mousasi a four-time World Champion.
 At the moment of his departure from UFC in July 2017, he was #4 in the official UFC middleweight rankings.
Star Market was a New England chain of supermarkets based in Greater Boston.
 It was owned by the Mugar family and started in 1915.
 The company was sold to The Jewel Companies, Inc. in 1964 and later to Investcorp, which in turn sold the chain to Shaw's Supermarkets.
 As stores were remodeled, many adopted the Shaw's name, leaving only a handful of Star Market stores operating by the late 2000s.
 In 2008, Shaw's began to revive the name, a trend which was expedited after the parent company of both chains was sold to Cerberus Capital Management.
 Today, both Shaw's and Star Market are administered as a single division.

 In its May, 2004, issue, Boston Magazine ranked the Mugar family sixth in its list of the 50 most influential Boston families.

Akihiro Gono (郷野聡寛 , Gōno Akihiro ) (born October 7, 1974) is a Japanese mixed martial artist.
 He is best known for his clever and deceptive fighting style, and for his flashy ring entrances.
 His fighting style is characterized by skillfully avoiding strikes, using fast counter punches and generally getting the opponent to fight his way.
 He is one of only four men to beat Bellator Middleweight Champion Hector Lombard, and one of six to beat the DREAM Light Heavyweight Champion and former Strikeforce Light Heavyweight Champion Gegard Mousasi.

 He had a natural gift for mimicry, and his impressions of celebrities such as Humphrey Bogart, Gary Cooper, Boris Karloff and many others were considered among the best.
 However, he also could imitate a housefly on a slippery oil cloth, neon signs, alligators, driftwood furniture, rubber bands, frozen chickens, frogs, praying mantis and—his favorite—an ostrich, all of which found their way into his act or in characters he played on TV.
