5x20 - 3rd Rock from the Sun

It's a nice day and Dick doesn't want to be stuck in the workplace, so he decides to do something that he thinks has never been done before - fake a sick day. Mary soon finds out what he's up to and decides to join him, and the pair run into Strudwick, who is doing the same thing. Meanwhile, Sally, Harry and Tommy find a police scanner that Don has left lying around and begin listening to a woman named Andrea's phone conversations. Things take an interesting twist, however, when Harry begins dating her.
