guest-host

Is it possible for Betty White to become any more popular? She's been famous in every era of her adult life. Now the Facebook campaign for her to be the guest-host on 'Saturday Night Live' has reached 188,000 cyber-signatures.

Whether people remember her from 'The Mary Tyler Moore Show' or 'The Golden Girls' (or even 'The Golden Palace') or her Super Bowl Snickers commercial, they want more Betty. While it's unlikely Lorne Michaels will do anything with 'SNL' that he doesn't want to do, this could be a publicity boon for the show. On the other hand, the public is very fickle when it comes to this sort of thing.

Can the 88 year-old actress even handle the stress of a rehearsal week followed by a late-night live show? Filming a commercial or a clip for '30 Rock' is one thing, but this would require a level of energy she may not have anymore.

Now where is that Facebook campaign for Abe Vigoda to guest-host 'SNL'?
