At St Peter's Basilica in Rome two elderly Cardinals were discussing the church's celibacy rule ahead of voting for a new Pontiff.
'So when's the last time you shagged an altar boy, then?' Eighty-something Cardinal O'Flaherty asked his colleague from Belgium.
'Let's see, now,' Cardinal Pierre, 81, replied, 'I think it was 1949.'
'Wow, that's such a long time ago, you're practically a saint!' O'Flaherty said.
'Not really, my friend,' Pierre answered, 'it's only just gone five past eight now!'
