[1] Hardcore, who had debuted in the World Wrestling Federation in 1994, introduced his on-screen "cousin" Crash Holly on August 16, 1999.

[6] After arguing over who was the toughest Holly cousin,[2] the pair brawled all over the arena for the rest of the show.

[8][9][10] From September on, the cousins started teaming together full-time,[11][12][13][14] during which time they took to the gimmick of claiming themselves to be well over 400 lb (180 kg), so they could be considered "superheavyweights".

[2] On October 18, 1999, on Raw is War, Crash and Hardcore won the WWF World Tag Team Championship together, defeating the Rock 'n' Sock Connection, after Mankind refused to tag into the match, and Triple H interfered.

[15][16] They held the title for two weeks before dropping it back to Mankind and his new partner Al Snow on the November 4 episode of SmackDown!.

[19] Crash regained the title the day after WrestleMania,[19] and soon after this, the Holly cousins had their last match as a team for over six months.

[19] Hardcore legitimately broke his arm in a match against Kurt Angle and was sidelined for most of this time.

[2] Originally the Hollys were supposed to reunite on September 2, 2002 when Crash revealed that he was the one who was leaving Raw, and planning to join his cousin Hardcore on SmackDown!.
