How many episodes of the British TV sitcom "Fawlty Towers" were made?

"Fawlty Towers" is a British television sitcom broadcast on BBC2 in 1975 and 1979. Only 12 episodes were made (two series of six episodes each). The show was created and written by John Cleese and Connie Booth, who also starred in the show. They were married at the time of series 1, but divorced before recording series 2. The show was ranked first on a list of the 100 Greatest British Television Programmes drawn up by the British Film Institute in 2000.

The series is set in "Fawlty Towers", a fictional hotel in the seaside town of Torquay on the "English Riviera". The plots centre on tense, rude and put-upon owner Basil Fawlty (Cleese), his bossy wife Sybil (Prunella Scales), comparatively normal chambermaid Polly (Booth) who often is the peacemaker and voice of reason, and hapless and English-challenged Spanish waiter Manuel (Andrew Sachs), showing their attempts to run the hotel amidst farcical situations and an array of demanding and eccentric guests and tradespeople.
