Episode #119 "Selfish Dick"

When Dick learns that Dr. Albright is getting a bigger, better office and leaving him with a new, eccentric office-mate, he's devastated and tries to make her change her mind, but she won't hear of it, so Dick quietly makes a few phone calls and she loses the office. He feels vaguely guilty about what he's done, but assures himself that his needs come first. While teaching Sally to make guacamole, Mrs. Dubcek cuts her finger and Sally faints. On the way to the emergency room, Sally gets dropped down the stairs. At the hospital, the aliens begin speaking like characters from every medical drama they've seen since they've been on the planet. They dress in lab coats they've found and create havoc until they're escorted out by security.
