Doctor in the House S05E10 - The Godfather

The Binghams' marriage is in crisis. Lawrence wants a son and heir but Mary wants to carry on with her medical career. Efforts on Lawrence's part to get Duncan to talk Mary round fail miserably and soon Dick and Paul have been roped into the argument. Since Mary's pet name for her husband is Badger, Duncan wheels a crib into the ward containing a badger to drop a hint in her direction but she explains that she is already pregnant.
