Life of Brian is without doubt the funniest film ever made (IMHO).
'What have the Romans ever done for us?'
'He's not the Messiah, he's a very naughty boy!'
'You're all individuals!'
(crowd all together) Yes, we are all individuals!
'I'm not the Messiah, now f**k off!'
...'How shall we f**k off oh lord?'
