The classic final scene in "A Case of Immunity" is very worthy of mention here, as the villain goes from high speed drive to a quick reverse in terms of arrogance. Columbo's trickery at its best and turns out to be funny with respect to where the murderer thought he was going.

In "Swan Song," Tommy Brown is clearly feeling very confident at the airport, actually laughing at Columbo's failure. Presumably Tommy's elation continues right up until the moment Columbo stuns him with the headlights in the woods, carrying the proof of his guilt -- almost literally a "deer in the headlights," if deer were murderers.

Oh man, when Paul Hanlon is at the gymnasium with the basketball practice, and Columbo tells him that not only was Mr. Wagner's house bugged, but so was Hanlon's. The way he breaths out a sigh of horror is beyond perfect. He goes from being super irate at Columbo for waisting his time to pretty much realizing he's going to jail for sure, in a matter of five seconds. LOL

Columbo: "So we checked your office, and you know what? Your phones are bugged too. By the same equipment and by the same man."

Paul Hanlon: "My phones?"

Columbo: "Yes sir. Bugged."
