Duncan and Paul want a colour television set for the doctors' common room but the Binghams want a table-tennis table as Lawrence professes to be excellent at the game. Dick stays neutral.

Dick and Paul are both useless as is Mary as the umpire and even Lawrence's shortcomings are eventually exposed.
