Adult Education - S4.E7

When Tom and Diana's life drawing art classes at the local college are terminated and complaining yields no joy, they decide to instigate their own at Bayview. Baines is to be the model, posing as Julius Caesar, bare beneath his toga for authenticity (or so Diana tells him).

When an inspector calls at Bayview, Diana undoes the knot holding the toga in place and leaving Baines publicly nude. As a result, he has to go to a clinic where Jane reports that he has had a breakdown.
