Yet another reason to be miffed with NBC during this late night fiasco: we're now never going to see Elvis on the 'Tonight Show' couch! Conan O'Brien took a couple more swipes at NBC-brass on his second-to-last show as the show's host -- lamenting about the guests who were to come.

"I'd like to apologize to the guests that were scheduled for next week," O'Brien joked. "President Barack Obama, the Pope, the queen of England and our good friend, Elvis Presley was stopping by."

Maybe he was joking about that one. But he might have only been half-joking about some of the celebs he has skewered over the past shows.
