When I worked at Cosgrove Hall, Mark Hall (one of the guys after whom the company was named) came round to inspect the progress of his creative team. He noted that in one storyline the doctor and patient's relatives were involved in a discussion at the patient's bedside. Mark, with his knowledge of hospital procedure, was able to point out to his silly creatives that a doctor would not be present during visiting hours.
One ungrateful storyboarder responded by pointing out that the patient in the story was a crow and the doctor was a pig.
