(1999.08.09) Chris Jericho's WWE/WWF Debut

The build-up to Jericho's arrival was a clock labeled "countdown to the new millennium," counting down over the weeks prior to his arrival. On the home video, Break the Walls Down, Jericho states he was inspired to do this as his entrance when he saw a similar clock in a post office. Vince McMahon gave him the green light to use it as his intro to the WWF. The clock finally ran down on August 9, 1999 in Chicago, Illinois while The Rock was in the ring doing a promo. Jericho, a heel, who was actually being cheered instead of getting booed, entered the arena and proclaimed himself "Y2J" (a play on the Y2K bug). The Rock proceeded to verbally mock him for his interruption.
