Insanity

MC (on the fact that I haven't watched the downloadable commentaries for the new Dr. Who episodes that the BBC has so kindly provided for each new episode after it's broadcast) : That's good .... maintain a bit of sanity. Don't get sucked in competely.
Me: well i have plenty of things to keep me insane
MC: I don't doubt it.
MC: Insanity is like a tonic.
Me: how so?
MC: Difficult to say, but I'm sure it's true.
Me: heh
