I know that Conan is huge and naturally towers over the guests, but I think you should exagerate the effect. Have Conan sit in a Judge Judy size desk or larger and the guests in a chair that's not as tall, but that they have to climb up into. Maybe have Max play on some synth drums for a show. He'll hate them. Go ahead, be funny Funny Man. Make me laugh! Ok, you're funny. Good day.
