#4 Kyle Busch as a guest on WWE RAW

Kyle Busch was never a WWE Superstar. Busch is a regular NASCAR racer and is known to have won multiple championships in that field. He achieved celebrity status by being so exemplary in racing. Busch is a two-time NASCAR Cup Series Champion and has twice won the Best Driver award.
Busch happens to be a WWE fan and was in attendance during the 12th February 2019 edition of RAW. The WWE 24/7 Champion R-Truth took the opportunity and invited Kyle Busch to celebrate with him not knowing that the Nascar driver had arrived that night to leave with a title around his waist.
Kyle Busch had all the reason in the world to celebrate that night. Later on in the episode, Busch was celebrating with his friend during a photoshoot. R-Truth capitalized on the opportunity that was presented before him and regained the WWE 24/7 Championship.
No one would have expected NASCAR champion Kyle Busch to ever hold the WWE 24/7 Championship. Even though it's monumental, rarely does anyone mention or remember the NASCAR driver's title win.
