Haha, I remember this. No Way Out (of texas) 1998. The Rock was priceless in that promo. He was just continually mocking to the camera, "I'm the Cha-aa-aa-amp" and do the mannerisms of knocking Shamrock out with the chair, funny! The Rock was a star already.
I can remember that time with the Nation of Domination. The Rock was growing as a star and was constantly arguing with Farrooq which led to arguments with other Nation members, who faced the DOA and Shamrock after Shamrock has snapped and beat some of the DOA up (unless that was at WM the next month.) Crazy, good-times!
