It wasn't that funny. Like others I as a young man found Monty Python patchy.
Life of Brian was funnyish with "naughty boy" etc, and very funny, but in an intentionally offensive way in the Calvary scene: Always Look on the Bright Side of Life. Ho, ho.
Controversial at the time (the charge was not blasphemy, but deliberately setting out to upset Christians as I recall). Big discussion on a "serious" channel betwen Cleese and Palin on the one hand, and Muggeridge and Southwark (I think) on the other.
Out-bidding each other on sanctimonious pretensions. MP got the "thirty pieces of silver" crap from Stockwood and Cleese and Palin doing "artistic integrity" and "critical enquiry" (wot dat den?) defenses.
At the time I was a fan of the film, but contemptuous of the conceits of its makers. Lobster quadrille stuff, that was.
PS: a question for all lovers of Life of Brian. What are the chances of a group of modern satirists making a film called "The Life of Mo". Does such a group exist? If not, can you explain why not? Assuming such a group does exist would it have the courage to make the film and have it distributed? And if not, can you explain why not/
