The fact that it didin't happen shows that he does have people around to reel him in when vince gets OUT THERE.
I'm betting this was one of those ideas that come up in brainstorming sessions.
Writer1: Can we do something with Steph's baby?
Vince & Steph: Yeah Sure.
Writer2: How about the child looks like Elvis.
Steph: what if Triple H isn't the father.
Vince: Oh that's good.
Writer1: What if you think it's an alien?
Writer2: Or another wrestler?
Vince: What if I'm the father?
Everybody: EWWWW!!! Gross!!!
Vince: Ok, Ok, that's a little out there.
Writer2: How about it's some genetic experiment with another of the female wrestlers.
Vince: How about Shane's the father!!
Everybody: EWWWW!!! Gross!!! Go get us some coffee old man!!
Steph: That's sick.
Vince: Ok, Ok, I'm just trying to help here.
