Yep I think it's when JB is at his absolute best, it's why he shines on talk shows. I also think that JB isn't disingenuous. The thing with DT is that he is always acting, even when being interviewed. Which is fine, it's his call and God knows that they have the right to not let their real selves show, but that works for an actor, not for comedy and ad lib things, they need to let the barrier down a little bit to be genuinely funny.
