"The Thin White Line" had all the earmarks of going embarrassingly over the top but, instead, Martin Milner gives his best performance in the entire series playing the accidentally drugged-up victim of a prank gone awry. After Tod is drugged he wakes into a psychotic break and, for the rest of the show, I was waiting for Milner to go over the top with affected behavior. Somewhat surprisingly he rides a perfect edge, giving a believable and very out-of-body performance, different from anything he did in the series before or after. Tod's break with reality is scary and, at moments, absolutely hilarious. Those who love Buz won't see much of him in this episode but his final scene with Tod is well done and, as often happens on Route 66, solidifies the strength of his relationship with Tod. This is a truly great episode. Someone has to explain to me, however, why a vendor is on an empty street selling hot dogs in almost complete darkness.
