To drive ratings up -- and to drive devoted pro wrestling fans up a wall -- Vince McMahon and World Wrestling Entertainment recently began welcoming guest hosts to take over Monday Night Raw -- the WWE's flagship show -- every week.

So far, everyone from the NBA's Shaq to Entourage's Jeremy Piven to ZZ Top has taken over the live two-hour wrestling show.

It seems that when the show producers can't find a celeb to fit the bill, they bring in a wrestling star from the past -- like The Million Dollar Man Ted DiBiase or Sergeant Slaughter.

While stunt casting like that helps to bring in more casual viewers, it tends to drive more devoted fans nuts by detracting from the in-ring action they tune in to watch. But, the practice allows for TV and movie promotional tie-ins for Raw -- while it also allows stars who are also long-time closet wrestling fans to live a dream in the squared circle.

But, as long as the ratings stay up, there's no limit to who could jump into Raw's command chair. Rumors have everyone from Bob Barker to Jerry Springer stepping through the ropes. Personally, I'm rooting for some real left field casting like Jane Seymour, Jim J. Bullock or Alan Colmes.
