Organ donation is the donation of biological tissue or an organ of the human body, from a living or dead person to a living recipient in need of a transplantation. Transplantable organs and tissues are removed in a surgical procedure following a determination, based on the donor's medical and social history, of which are suitable for transplantation. Such procedures are termed allotransplantations, to distinguish them from xenotransplantation, the transfer of animal organs into human bodies.

As recently as the late 1960s and early 1980s, irreversible cardiopulmonary failure was the only standard for determining death for purposes of donation after cardiac death. This was replaced by brain death, the irreversible loss of all function, including the brain stem, though donation after cardiac death is a resurgent source for transplantation.

The laws of different countries allow potential donors to permit or refuse donation, or give this choice to relatives. The frequency of donations varies among countries.

Monty Python (sometimes known as The Pythons) was a British surreal comedy group who created Monty Python's Flying Circus, a British television comedy sketch show that first aired on the BBC on 5 October 1969. Forty-five episodes were made over four series. The Python phenomenon developed from the television series into something larger in scope and impact, spawning touring stage shows, films, numerous albums, several books and a stage musical as well as launching the members to individual stardom. The group's influence on comedy has been compared to The Beatles' influence on music.

The television series, broadcast by the BBC from 1969 to 1974, was conceived, written and performed by members Graham Chapman, John Cleese, Terry Gilliam, Eric Idle, Terry Jones, and Michael Palin. Loosely structured as a sketch show, but with an innovative stream-of-consciousness approach (aided by Gilliam's animation), it pushed the boundaries of what was acceptable in style and content. A self-contained comedy team responsible for both writing and performing their work, the Pythons' creative control allowed them to experiment with form and content, discarding rules of television comedy. Their influence on British comedy has been apparent for years, while in North America it has coloured the work of cult performers from the early editions of Saturday Night Live through to more recent absurdist trends in television comedy. "Pythonesque" has entered the English lexicon as a result.
