Alas Smith and Jones indeed that wonderful Mel and Griff Rhys should have got involved in this fifth-form farce about four low-IQ aliens at large on earth. Fortunately, both they and Jimmy (Spender) Nail have moved on to more suitable fare since. Best gag has Mel rescued from spacedrift by a repulsive alien who gives him the galactic heave-ho after finding that he isn't the right sex. Don't stay awake waiting for further laughs: there aren't any.
