Brian Yandrisovitz (born May 6, 1964 in Allentown, Pennsylvania), better known as Brian Knobbs, is an American professional wrestler, best known as one half of the tag team The Nasty Boys along with Jerry Sags.
Knobbs' wife is the sister of Greg "The Hammer" Valentine's wife.
Knobbs started his career in the American Wrestling Association as the masked Terrorist in 1985. In 1986, he formed a tag team called The Nasty Boys with Jerry Sags and wrestled in the Tennessee territory until they moved to Florida Championship Wrestling, where they won five Tag Team Titles from 1988 through 1990.
In 1990, they went to the NWA's Jim Crockett Promotions which had been purchased by Ted Turner and would be renamed World Championship Wrestling before they left a few months later. They feuded with Rick and Scott Steiner over the U.S. Tag Team Titles but could not defeat them. In late 1990, they went to the World Wrestling Federation (WWF) where they were managed by Jimmy Hart and won the World Tag Team Titles from The Hart Foundation before feuding with and losing the titles to the Road Warriors. They turned face in the fall of 1992 to feud with Jimmy Hart's Money Inc. over the tag team titles, but were unable to recapture the gold.
They left the WWF for World Championship Wrestling (WCW) in 1993 and were quickly placed with manager Missy Hyatt, who led them to the World Tag Team Titles. She left them and they went on to feud with Harlem Heat, The Blue Bloods, and the team of Dick Slater and Bunkhouse Buck. They won the tag team titles a second time later in 1993, and were defeated by Cactus Jack and Kevin Sullivan the following year. In May 1995, they defeated Harlem Heat for their third and final WCW tag title on Main Event, but lost the belts back to Harlem Heat on a June episode of WCW WorldWide.
In 1996, they were tricked by the nWo into thinking they were going to become members but were attacked as soon as they received their shirts. Sags had been injured previously in a shoot-altercation with an intoxicated Scott Hall and he had to retire due to this injury.
Following Sags' retirement, Knobbs became a singles wrestler and entered WCW's hardcore division. He feuded with Norman Smiley and Bam Bam Bigelow and won the title three times. He is also famous for losing the belt simultaneously to all three members of the boy band stable Three Count, making them the first and only co-holders of that belt, and regaining it from them later. Fit Finlay was briefly his manager as the "Hardcore Soldiers" with partner "The Dog".
Sags returned to wrestling in 2001 with Knobbs as The Nasty Boys to wrestle in the short-lived X Wrestling Federation and they both retired after it folded in 2002. Knobbs has since returned to wrestling, including wrestling at the New Alhambra Arena (formerly ECW Arena for Pro Wrestling Unplugged on Saturday, June 16, 2007. On November 20, 2007, Knobbs and Saggs reformed as The Nasty Boys at the SmackDown! tapings from Tampa, Florida to wrestle their first WWE match in years. According to reports, the match was disastrous and the team were accused of unprofessionally working stiff with their opponents, Dave Taylor and Drew McIntyre. The Nastys have not returned to a WWE ring since.
