I can imagine Brian Williams and his superiors at NBC had some discussions about whether he should host “Saturday Night Live.”

But he’s really quite funny — playing characters, not just versions of himself.

And, if the fellow who turned up in the opening sketch didn’t think SNL would hurt his credibility, Williams might not need to worry either. (No, I don’t mean Horatio Sanz. I mean the other surprise guest, the one who got to say “Live, From New York….”)

I was surprised that Don Pardo read the promo announcement for next week’s show (Duane “The Rock” Johnson and Amy Winehouse), since it seems to be conventional wisdom that there will be no next week’s show due to the scheduled writer’s strike.
