I'm an Artie fan, but it's getting harder to root for him. The core of his argument is simply bullshit. "No, no, I only lie on the air for entertainment purposes, and then it's only having to do with drugs." HUH? But he's so offended that Gary can't trust him anymore. Typical bullshitter's deflection. Ignore the real problem and concentrate on a technicality.
ARTIE IS A HEROIN ADDICT. He will crash and burn, and it will be ugly.
