Watford Central was a planned station on the London Underground in Watford, Hertfordshire.
 The station was to be part of a proposed extension of the Metropolitan line from the present-day Watford tube station to Watford's High Street opposite Clarendon Road.
 Had the line been built, Watford Central would have been the terminus of the branch line.
 The building which was planned to be the station booking hall has long gone, however the facade was retained and a new building constructed behind it.
 It is now "The Moon Under Water" public house.
The Muppet Show is a family-oriented comedy-variety television series that was produced by puppeteer Jim Henson and features The Muppets.
 After two pilot episodes produced in 1974 and 1975 failed to get the attention of network executives in the United States, Lew Grade approached Henson to produce the programme in the United Kingdom for ATV.
 The show lasted for five series consisting of 120 episodes which were first broadcast in Britain between 5 September 1976 and 15 March 1981 on ATV and was shown by the other ITV franchises in the United Kingdom.
 The programs were recorded at Elstree Studios, England.
A repatriation tax holiday is a tax holiday specifically directed towards individuals and businesses in one country who repatriate to that country income earned in other countries.
 The theory supporting such an action is that multinational companies headquartered in one country, but which earn income in a second country will be unlikely to bring income from the second country back to their home country if high taxes will be assessed on this income when it is brought back.
 By allowing those companies to bring income back to the home country at a reduced tax rate, money will be injected into the economy of the home country that otherwise would remain in the second country.
Watford Palace Theatre, opened in 1908, is an Edwardian Grade II listed building in Watford, Hertfordshire.

A foreign worker or guest worker is a person who works in a country other than the one of which he or she is a citizen.
 Some foreign workers are using a guest worker program in a country with more preferred job prospects than their home country.
 Guest workers are often either sent or invited to work outside their home country, or have acquired a job before they left their home country, whereas migrant workers often leave their home country without having a specific job at hand.
