The Rock continued to feud with Mankind over the WWF Championship, which was traded back and forth between them. First, in the main event of the January 4, 1999 episode of "Raw Is War", Mankind defeated the Rock after interference from Stone Cold Steve Austin. Then at the Royal Rumble on January 24, the Rock regained the title in a brutal “I Quit” match, a type of match that only ends if one of the combatants says “I quit” on a microphone. Intended to show a vicious mean streak in the Rock's character, this match went horribly wrong as at the end of the match the Rock hit Mankind in the head with a steel chair 11 times instead of the scripted five, five shots already being a risky amount (most wrestling matches in the Attitude Era involving steel chairs had at most 2 or 3 shots to the head). After the 5th shot, Mankind was still at ringside instead of being two-thirds up the entrance ramp where he was supposed to be, and after the eleventh shot which knocked a bloodied Mankind out, a recording of Mankind saying "I Quit" from an earlier interview was played over the public address system. On January 31, during an episode of "Sunday Night Heat", the Rock and Mankind participated in an Empty Arena match, a match that took place in an arena with 22,000 empty seats where any part of the facility could be used to contest the match. After 20 minutes of chaotic brawling in the ring, the stands, a kitchen, the catering area, an office, the arena corridors and finally a basement loading area, Mankind pinned the Rock using a forklift truck to win the WWF title. This match was referred to as "Halftime Heat" as it was televised during halftime of that year's Super Bowl. The two faced off again, at , in a Last Man Standing match which ended in a draw, meaning Mankind retained the title. Their feud ended on the February 15 "Raw Is War", when the Rock won his third WWF Championship in a Ladder Match after a debuting Big Show interfered on his behalf. The Rock then lost the WWF Championship to Stone Cold Steve Austin at WrestleMania XV.
