Oct. 13 (UPI) -- Serial record-breaker David Rush teamed up with a longtime collaborator on the sidelines of FOX game show 99 to Beat and recaptured a fist-bumping Guinness World Record.

Rush and Jonathan "Hollywood" Hannon, who are both contestants on this season of 99 to Beat, took some time out of filming in London to attempt the Guinness World Record for the most alternate fist bumps in 30 seconds (team of two).

Rush originally set the record at 380 with Howie Mandel on the set of America's Got Talent, and later broke his own record with 398 when he teamed up with YouTuber Dr. Mike.
