3rd Rock from the Sun

S6 E15: Glengarry Glen Dick

After hearing a pitch for a timeshare, Dick is sold and, unable to afford it entirely, he convinces Don to pay the other half. When Dick, Mary, Sally and Don take their first holiday there, however, they find it to be dismal; small and windowless, with nothing in the surrounding area but a prison. Meanwhile, Tommy has finally outgrown Harry, leading Harry, paranoid that he is shrinking, to consult a doctor.
