3rd Rock from the Sun

Four extra-terrestrials suddenly materialize in the college town of Rutherford, Ohio. Disguised as humans, they name themselves the Solomons - Dick , Sally, Tommy, and Harry. On the surface, this family functions as normal as possible, but underneath they are out of sync with every person on the planet. Their mission from The Big Giant Head is to study a confusing planet and its confounding inhabitants while trying to gain acceptance on Earth. Welcome to Earth, Baby!
