The main-event match on the July 6, 1998 WCW Monday Nitro in which Goldberg defeated Hollywood Hogan for the WCW World Heavyweight Title was not only the greatest Moment of Awesome for Goldberg's career, but arguably for WCW, and certainly for Nitro. More fans were in attendance at that show than at any other WCW event before or after.
Goldberg held The Giant (aka Big Show) in the air for a full two seconds before finishing the move.
The Streak...untill the very end, that is...
And even then, it took Scott Hall cattle-prodding him in the face to make him go down (plus a series of other wrestlers attempting to help Nash before that).
His match against Diamond Dallas Page at Halloween Havoc 1998 was one of the best matches of his career.
While their eventual dream match was a stallfest not worth writing about, Goldberg making his awaited WWE debut interrupting The Rock of all people whipped the RAW crowd into a frenzy, esp. when Goldberg briefly got on the mic:
Goldberg: So, Rock?! You wanna know who's next?...YOU'RE NEXT! *spears Rock*
Not to mention the announcers' reactions to Goldberg's first appearance. Maybe it was scripted, but just the way J.R. says it tells you everything.
Jim Ross: It's... it's HIM!
Goldberg spearing Nunzio about the length of a half-ring during the 2004 Royal Rumble. Shared credit goes to the victim for a terrific sell job.
A non-wrestling one: his appearance on Joes vs. Pros, where in a round of "who can hit a golf ball closest to the pin", Goldberg was picked first by the Joes, because the challenger reasoned that Goldberg was too muscular to properly get his arms around to swing. Goldberg proceeds to drop the ball within two yards of the hole, a hole that was set up 350 yards away, closer than anyone else on the show.
