The Permissive Society

=Summary= Having failed again to get a date with Philip, Ruth is unhappy so Rigsby, to arouse her, blows in her ear but she just thinks there's a draught. Alan and Philip have been on a double date and Philip is annoyed that Alan is so inexperienced with women that they only ended up playing scrabble. Philip lost his virginity on his fourteenth birthday. Alan only got a bike for his. To prove he is not afraid of women Alan enters Ruth's room in his dressing-gown but hides in the wardrobe when Rigsby also goes in and, on discovery, pretends he was sleep-walking. Alan's girl-friend's father comes round to accuse Alan of upsetting his daughter and mistakes Rigsby for the lad's father. Rigsby and Alan see him off but lock the door when he returns with his muscle-bound sons.
