If you enjoy Cleese & all the British 'Pythonesque' humour of the time, then this little gem is absolutely hilarious.
Arthur Lowe is a real treat!
I saw this with friends on TV when it first came out, and its classic quotes have formed a part of our jokes for 30 years, and will do forever! I have it on tape and it is continually appreciated.
Perhaps some reviewers are taking it too seriously.
I can't believe it is now only available in the US (NTSC of course), and not in UK, where it should be an essential part of the history of British humour!!
