Seen any good movies lately?
Four couples are going to the movies. Each row holds eight seats. Betty and Jim don't want to sit next to Alice and Tom, and Alice and Tom don't want to sit next to Gertrude and Bill. On the other hand, Sally and Bob don't want to sit next to Betty and Jim. How can the couples arrange themselves so that they all sit in one row and still be happy.
