3rd Rock From The Sun

Four aliens come to Earth to learn about our customs and experience life on our planet. Posing in human form, they avoid detection. They report their findings back to the Big Giant Head (played by William Shatner). The commander (played by John Lithgow) takes the name of Dick Solomon and finds work as a college professor. The military expert, Sally Solomon, (played by Kristen Johnston) assumes the role of Dick’s sister. Oldest of the group and their intelligence officer assumes the role of Dick’s teenage son, Tommy Solomon. And then there’s Harry Solomon, Dick’s brother, who just seems to be along for the ride. The extraterrestrial quartet pretending to be human beings embodies the humorous “fish out of water” trope as they experience the human condition. This half hour primetime comedy series lasted six seasons.
