3. The Janitor - Scrubs
Definitely one of, if not the best character of Scrubs. I don't honestly know if he should count as a villain but seeing as he made it a point to torture and put John Dorian through hell at every chance he got, we'll call him a villain and that means I can stick him in the top three, wanna fight about it? But as much of a jerk that he is we just cannot help but love every second of him when he's on screen. Neil Flynn is perfect and if they casted anyone else it would have been awful. You never expect the things that he will do to John Dorian. The most memorable instance of this is when JD is riding through the parking lot on his scooter and he decides to drive over a puddle BUT IT'S NOT A PUDDLE! He drops down straight into the pit hole filled to the top with water. Hilarious!
