Something that made me chuckle and wonder WTF... in the scene where Dr. Collier brings his friend into the "Zoo" with the lab animals and he later goes over to the window and sees Columbo looking at his tires... the lady Dr., Dr. Borden is working on an experiment with a mouse in a maze, it seemed like such a trivial experiment, like that's the kind of experiments you do in high school science class... but the ending with the blind g** and his brother is one of the best Gotchas ever
