Richard is terrified to wake up to Hyacinth smiling at him and even more terrified when he realises he's forgotten their wedding anniversary. He saves the day when he decides to have an alarm system installed, claiming it is Hyacinth's "surprise" anniversary present and Hyacinth verbally harasses the representative and his employees as she wants an alarm in 'dusky pink'.
