In response to the idea of guest-starring on The Office, Steve Carell said:
No, it hasn’t been discussed. Do you really think that people want to see Michael Scott again? I think the people who say they want to see Michael Scott reappear would be ultimately slightly disappointed. I think you always wish for something that you don’t sincerely want to come true. And I think in a way it’s better to imagine where Michael and Holly are at this point than actually see it.
Ok, that’s fair. But how about Ping or Agent Michael Scarn or Prison Mike or Michael Klump or Blind Guy McSqueezy or Caleb Crawdad?
