I think Jake and Conan have great chemistry. I love the interviews/appearances Jake did on his show. 

I completely agree...when Jake has someone like that to spark off, he's on a roll. Conan seems to bring out the off-beat side, which is brilliant...It's the same with Ellen, you can tell there is genuine affection and admiration on both sides, plus they are both really funny people...its a joy to watch them interact.
