UFC 37.5: As Real As It Gets was a mixed martial arts event held by the Ultimate Fighting Championship at the Bellagio Hotel and Casino in Paradise, Nevada on June 22, 2002.

The fight card was headlined by a bout between Vitor Belfort and Chuck Liddell, with the winner getting a shot at the UFC Light Heavyweight Championship. UFC 37.5 was the first UFC event to feature Joe Rogan as a color commentator, but he would leave again to host Fear Factor, and return at UFC 40. Joe made his first and only UFC appearance prior to UFC 37.5 as the behind-the-scenes interviewer at UFC 12.

UFC 37.5 was a last-minute event specifically held to promote the UFC on Fox Sports Net's The Best Damn Sports Show Period, where the "best fight" of the night was to air during the BDSSP's "All Star Summer" celebration in June 2002. The fight aired was Steve Berger vs Robbie Lawler, which has the distinction of being the first mixed martial arts fight to be aired on US cable television.

The event featured only six fights, which is a much smaller card than others under the UFC banner at the time, and was the first event since UFC Japan not to be broadcast live on pay per view. The event was later broadcast on pay-per-view in its entirety. The number 37.5 was used because UFC 38 had already been announced and marketed in England, where the UFC was making their debut just three weeks later.

UFC 37: High Impact was a mixed martial arts event held by the Ultimate Fighting Championship at the CenturyTel Center in Bossier City, Louisiana on May 10, 2002. The event was seen live on pay per view in the United States, and was later released on home video.

The card was headlined by a Middleweight Title Bout between Murilo Bustamante and Matt Lindland, and featured the first UFC appearances of Robbie Lawler and Ivan Salaverry.

The fight between Bustamante and Lindland has led to the contest being known as the infamous "double tap" fight. Bustamante had Lindland hooked cleanly in an armbar early in the fight, then released it after what seemed to be a tap, followed by a shout to stop the action by John McCarthy. Lindland claimed it wasn't a tap, which controversially led McCarthy to restart the fight. Many thought that this was a mistake by McCarthy to stop the fight considering it was probably the only way for Lindland to escape the armbar.

Bustamante was stripped of the title in October 2002 after signing with PRIDE, thereby vacating the UFC Middleweight Championship belt.

Belfort was born in Rio de Janeiro and studied jiu-jitsu with the Gracie family, namely Carlson Gracie. He received a black belt under Carlson and currently trains with Xtreme Couture, fighting in the middleweight division. He is currently ranked as the #3 middleweight in the world by MMA Weekly.

Belfort also had a small part in a reality show on Brazilian television and appeared next to his wife when she was photographed for the Brazilian edition of Playboy.

On January 9, 2004, Vítor's sister, Priscila Belfort disappeared and the relatives received no information about her. In August 2007, a woman (identified as Elaine Paiva) confessed that she participated in her kidnapping and killing and that she was kidnapped to pay off a four thousand dollar debt Paiva had with drug dealers. Paiva was arrested along with three others alleged to be involved in the kidnapping. The group allegedly buried her body in the woods in Rio de Janeiro where police conducted searches but her remains have never been found. Her family however do not accept this version and believe that Priscila is still alive somewhere. Vítor still maintains a missing sign in the Brazilian version of his website.
