I had my first exposure to Monty Python as a very young child, when their shows were first being broadcast in the US in the mid '70s and my folks would watch them.  Then I saw this movie on Cinemax around 1982...and again the following day.  (By the way, Spiny Normal gives it two prickly thumbs up...Dinsdale!)  After which I promptly went out and bought...*dramatic pause*...a SHRUBBERY!! *Dramatic music!*  I laughed, I cried, I wet my pants (well, all right, not really), I did a few Silly Walks.
