Thanks for the Money (Part 1)

A woman's memory lapse and her forgetfulness proves almost fatal when she sets her house on fire. Shirley develops a severe case of triskadekaphobia – a fear of the number thirteen. Matron Sloan is acting like a bear with a sore head, all because of a toothache and her fear of dentists, although she soon comes to her senses when Terence threatens her with a pair of pliers.
