A post box (British English and others, also written postbox, known in the United States and Canada as collection box, mailbox, post box, or drop box) is a physical box into which members of the public can deposit outgoing mail intended for collection by the agents of a country's postal service. The term post box can also refer to a private letter box for incoming mail.

Varieties of post boxes (for outgoing mail) include:

In 1653, the first post boxes are believed to have been installed in Paris. By 1829, post boxes were in use throughout France. The first public post boxes in Poland were installed in Warsaw in 1842.

In the British Isles the first pillar post boxes were erected in Jersey in 1852. Roadside wall boxes first appeared in 1857 as a cheaper alternative to pillar boxes, especially in rural districts. In 1853 the first pillar box in Britain was installed at Botchergate, Carlisle. In 1856 Richard Redgrave of the Department of Science and Art designed an ornate pillar box for use in London and other large cities. In 1859 the design was improved, and this became the first National Standard pillar box. Green was adopted as the standard colour for the early Victorian post boxes. Between 1866 and 1879 the hexagonal Penfold post box became the standard design for pillar boxes and it was during this period that red was first adopted as the standard colour. The first boxes to be painted red were in London in July 1874, although it would be nearly 10 years before all the boxes had been repainted.

Box (plural boxes) describes a variety of containers and receptacles for permanent use as storage, or for temporary use often for transporting contents. The word derives from the Greek πύξος (puxos), "box, boxwood".

Boxes may be made of durable materials such as wood or metal, or of corrugated fiberboard, paperboard, or other non-durable materials. The size may vary from very small (e.g., a matchbox) to the size of a large appliance. A corrugated box is a very common shipping container. When no specific shape is described, a box of rectangular cross-section with all sides flat may be expected, but a box may have a horizontal cross section that is square, elongated, round or oval; sloped or domed top surfaces, or non-vertical sides.

A decorative or storage box may be opened by raising, pulling, sliding or removing the lid, which may be hinged and/or fastened by a catch, clasp, or lock.

Several types of boxes are used in packaging and storage.

Depending on locale and specific usage, the terms carton and box are sometimes used interchangeably.

Mr. Bean is a British comedy television programme series of 14 half-hour episodes written by and starring Rowan Atkinson as the title character. Different episodes were also written by Robin Driscoll, Richard Curtis and one by Ben Elton. The pilot episode was broadcast on ITV on 1 January 1990, with the last television episode, "Goodnight Mr. Bean" broadcast on 31 October 1995. The final episode, "Hair by Mr. Bean of London", was a video exclusive released on 15 November 1995, but not broadcast in the UK until 2006.

Based on a character originally developed by Atkinson while he was studying for his master's degree at Oxford University, the series follows the exploits of Mr. Bean, described by Atkinson as "a child in a grown man's body", in solving various problems presented by everyday tasks and often causing disruption in the process. Bean rarely speaks, and the largely physical humour of the series is derived from his interactions with other people and his unusual solutions to situations. The series was influenced by physical performers such as Jacques Tati and comic actors from silent films.
