Tidbit from "The Rise and Fall of ECW" doc: Paul E. wanted Steve Austin to become ECW World Champ, but Austin turned that down in favor of putting over Mikey Whipwreck, just so his character could come right back and say, "Yeah, I lost, but I was THIS close to becoming Champion, and now I'm hungrier more than ever before."
Don't know if it's a fact or a rumor, but supposedly plans were made for an AJ Lee vs. Lita feud for WrestleMania XXX that got rejected (Punk might or might not have influenced that decision, if it's even true or not.)
NO ONE was ever allowed to rib The Undertaker back in the day, except for Paul Bearer and vice versa. Bearer's nickname for Taker was "Wendy" due to Taker's red hair.
Also, The Undertaker has an abject fear of cucumbers. This was also revealed by Bearer.
As revealed on the "McMahon" documentary DVD, Vince wanted to do an incest angle involving Shane and Stephanie, as well as Vince revealing himself to be the "father" of Stephanie's baby. Don't know if both those ideas were related or different, but I remember them being discussed. Gotta rewatch it. Also, that I Quit match he had with Stephanie where he choked her out with a steel pipe? That was literally DAYS before she had her IRL wedding with Triple H.
