Roger Smith (voiced by Seth MacFarlane) is one of the main characters in the animated comedy series American Dad!.He is a space alien (whose appearance resembles that of the greys) living with the Smith family. Roger is sarcastic, self-centered, surly and speaks in swish.
Roger's species can "learn others' memories" through anal probing. Roger came to live with the Smith family after saving Stan Smith's life in Area 51. He has lived with the Smiths for four years.
Roger's flamboyant talking pattern is a parody of Paul Lynde. He can speak four different human languages; English, Spanish (though not fluently), French and Armenian. On his home planet, he was a greeter at a Wal-Mart-analogue store called Philaxido.
Little is known about Roger's past; his planet is never seen or described in-depth, though according to him, it sounds fairly similar to Earth, though in a deleted scene, it is also mentioned to be four hundred degrees colder. He has mentioned that snow reminds him of his home planet, and figure skating apparently exists there; he also comments that he enjoys the cold in, and expresses bewilderment when his human friends begin to freeze to death. He has also commented that the planet has stores like Wal-Mart (where he was once a Greeter) and colleges.
He also states that his home planet is full of chickens, warning Hayley against "giving them the vote".
