I'm surprised The Rock vs Chris Jericho hasn't been mentioned yet. Perhaps it's because it was booked to make Jericho a superstar and that never quite happened, and perhaps it's because compared to other feuds, it was relatively short, but in a three month time span, they managed to produce two legitimate ****+ matches and one other very good one, turn Jericho heel and put him in main events, raise Rock's game and deliver some of the best banter we'd seen all year, if not in longer time. Highlights for me were Rock confronting a blood-soaked Jericho about accidentally hitting him with a chair and Jericho punching him, Jericho "accidentally" brushing into Rock and nearly knocking him over, Rock telling Jericho to stay out of his business while Jericho looks on at ringside while he's getting beat down by a group of heels, Rock telling Jericho he's just not that good and can't be a headliner, Jericho giving Rock a people's elbow, Jericho bringing Rock's belt nameplate to him since he won't need it anymore and Rock retaliating by handing him a chair for their rematch, Jericho and Rock playing the tag team partners who hated each other, Jericho attacking Rock out of frustration that Austin pinned him at Survivor Series which nearly put the entire company out of business, Jericho pinning Rock with the Rock Bottom on three separate occasions, Jericho gloating about beating Rock and Austin at ringside while sitting poolside with his belts and of course, the infamous "I am not a joke!" promo. Goodhelmet once said, and I agree, that this feud should have spanned the course of a year with them running the gauntlet and doing every imaginable gimmick match under the sun.
