I will say there was quite a few that impressed me. For starters, yes, Jerichos' return in 2007, although it turned out to be the worst kept secret, however, the marketing gimmick behind it was probably the most GENIUS thing behind it. I loved the moment he appeared interrupting Orton's little spotlight. Another one, I don't know if you'd call it a real comeback or not, but RVD at I think Raw's 15th anniversary show when Santino challenged anyone from the back to come out, and then RVD made that ONE NIGHT ONLY appearance at the Royal Rumble (Sorry, I don't remember what year it was.) But I was totally like
. I was so screaming my head off. Then of course, when Christian came back out of nowhere as Swagger was making his th-peech at the beginning ECW one night, I think the whole audience was taken by surprise too, as well as announcers. Most people were anticipating him at Royal Rumble earlier that year as part of the Hardy Bros story, but since he didn't appear then, we though he just wouldn't show up until WAYYYY down the road.
Then, I will say, after HBK was punted out by RKO, when he showed up after Orton was instructed to go to the backstage and bring HHH out to congratulate him, I think the whole audience freaked out, as well as me.
But one, that I think many people are overlooking, or at least in my eyes, has to be No Mercy, 2006.
Regal is having TERRIBLE night. He just has run in after run in with star after star backstage, and then gets chased out backstage nude and runs into Teddy Long who orders him to a match. Then he goes out to the ring. Nobody knows who he's going to fight. It seems like forever, then all of a sudden, you hear the familiar music of "Whatever" by Seven Mary Three, and out walks Chris Benoit, and the PPV is in the home state of Atlanta (where he lived.) and the arena goes apeshit, even JBL and Michael Cole are going nuts. I was floored, and still do get starry eyed, Benoit had gone on a little sabbatical for a while and that was his return match.
