Potential replacement names are already floating around including Olivia Munn, Chris Hardwick, Joel McHale, and Chris Rock, but Stewart tells "Extra" he is not sure who should take over, "I don't know man, I'm looking forward to seeing who they end up picking."

When asked if he will have a say in the decision he quipped, "I don't think they let you do that, do they let you do that when you leave a job, you just get to pick whoever it is." Jon joked, "I'm assuming someone around my size so they can save on the suits, I came in for Kilborn, he was six five so they just had to bunch them up in the back for me."

Jon saying he may have some special guests as the show comes to an end, but he just wants to focus on doing a good job, "I just hope we're able to keep doing it well to the end, don't want to get senioritis too bad, just end up playing ultimate Frisbee to bad, so hopefully I'll stay focused."

Extra also asked Stewart about speculation he could trade jobs with embattled NBC Nightly News anchor Brian Williams, Stewart quickly shutting that headline down: "Sounds like a terrible premise for a movie and nothing to do with what this would be."
