bumwin 

A majestic and mythical creature. It is generally a very cheerful and sociable animal that enjoys the company of other creatures, mainly rabbits.
Often hard to communicate with as it has a tendency to sleep at abnormal times, and has no exact sleeping pattern. It is neither nocturnal nor diurnal, and its sleeping patterns is hard to predict. It exists predominantly on a diet of curry and baffles medical science as it never appears to suffer from malnutrition. You will be very lucky if you come across a bumwin, as they are a rare and endangered species.

Bumping the lamp 

To go above and beyond expectations when completing a given task/project.
A genericized phrase originally used within the animation industry and the film industry as a whole. Based on a scene from the 1988 mixed live-action/animated film 'Who Framed Roger Rabbit' in which the main live-action character, Eddie Valiant, bumps into a ceiling lamp whilst handcuffed to the main animated character, Roger Rabbit, causing the lamp to continually swing back and forth throughout the remainder of the scene.
The term refers to how the animators went on to meticulously hand-draw unique shadows for the animated character for every frame of the scene.
The phrase went on to become a company mythos for the Walt Disney Company, then as a guiding principle within the greater film industry, and now sees use generally.

We follow the mythos of 'bumping the lamp' with the service at our veterinary practice.
