Was just reading the WM article, and they mentioned several WWE debuts for guys like Hogan, and Orndorff. It's fun the remember when a noted wrestler makes his first appearance for a new company.
Jericho's Raw debut on August 9th, 1999 in Chicago, Illinois interupting the Rock's promo.
Undertaker's Survivor Series debut.
Not sure when, but Steve Austin's WWE debut has I believe the Taskmaster Ted Dibiase's milliondollar champion or something like that.
The four radicals in I believe Pittsburgh.
Ric Flair on Superstars for his initial run in the WWE.
Scott Hall on Nitro sometime in May. Maybe Memorial Day.
