I've heard from more than one person who actually works for him that he is a stand up guy who always looks out for people with talent and work ethic, and that he's incredibly chill outside of work.
Norm or Conan alone could make that man cry any time they wanted. He hides behind food while they are on the front lines of abusive comedy. Eat some more food, Gordon, you'll be funny one day.
This has been discussed before, watch his UK tv shows. Gordon's evil boss persona has been build for the USA tv, because american audiences can't watch a reality show without bullshit melo-dramatic antics. Gordon is a very relaxed guy.
