All Creatures Great and Small: Promises to Keep

A comical episode of the long-running drama series based on the books, by James Herriot about his experiences as a Yorkshire vet. The gents might need to cross their legs, though. Tristan castrates a pig but forgets to dispose of the 'off-cuts', which still contain anaesthetic. When the farm cats eat them, they all pass out. The vets try to help an old lady who is having trouble keeping her farm going.
