"The decision by Cleese and Booth to quit before a third series has often been lauded, as it ensured an avoidance of the possibility that the show's immediately-high status could be weakened with lower quality work later down the line. (Cleese in particular was most likely motivated in making the choice by the end of his involvement with the Monty Python's Flying Circus TV series, which he departed after claiming to have run out of ideas for sketches.) Subsequently, it has inspired the makers of other shows to do likewise. Most notably, Ricky Gervais and Stephen Merchant refused to make a third series of either The Office or Extras, citing Fawlty Towers' short lifespan as the reason. Rik Mayall, Ben Elton and Lise Mayer, the writers behind The Young Ones, which also only ran for two series (each with six episodes likewise), used this explanation too. Elton also took the decision to end his next sitcom, Filthy Rich & Catflap, after only one series, despite its popularity."
