2005: The first man drafted in WWE's newly-formatted Draft Lottery (5 picks for RAW, 5 for SmackDown) was none other than then-WWE Champion John Cena coming over to RAW, fresh off his feud with JBL. It would also be the first time since the initial brand split that both the WWE (Cena) and World Heavyweight (Batista) champions were on the same show, before Batista was moved over to SmackDown. Cena's remained a staple of RAW to this day, going on 11 years!
1998: Wrestlepalooza '97, presented by ECW, was headlined by the ECW Heavyweight champion Terry Funk retaining his title against Chris Candido, a surprise appearance by Jerry "The King" Lawler, and Tommy Dreamer picking up his first (televised) victory over longtime nemesis Raven in a "Loser Leaves ECW" match.
1993: At a WWF live event in Albany, New York, Shawn Michaels defeated Marty Jannetty to win the Intercontinental Championship in what would be the 2nd in a series of three matches for the IC Title between the former Rockers. This would also be the match where Kevin Nash made his official WWF debut as HBK's bodyguard, Diesel.
