3rd Rock from the Sun (season 2)

'Evil Dick' proceeds to take over the Solomon family and boss them around. He asks them to fetch a list of materials with which he secretly plans to spawn his own private army of clones; he then asks Mary to dinner at his house, hoping to lure her into bed. Just as Sally, Harry and Tommy have had enough of 'Evil Dick', Harry discovers that the real Dick is still locked in the basement. The Solomons free the real Dick, who arrives upstairs to find his evil counterpart wooing Mary in the living room. Dick is upset by this, and retreats outside to the Rambler, but his family tell him that they've had enough of his evil counterpart, and convince Nice Dick to take on and defeat Evil Dick.

Now that he is growing closer to Mary, Dick begins to feel that he should tell her the truth about where he and the others really come from. Unable to find the right situation in which to do this, however, he takes his family to a sci-fi convention, where Sally falls in love with the room service at the hotel, orders far too much, and racks up an enormous bill. At the end, George Takei is given the bill of $30,000.
