Jesus hangs from the cross while a crowd - Peter among them - gathers to watch. Jesus says: 'Peter, come here, I need to tell you something.' Peter steps forward to answer his messiah's call but a centurion steps forth, unsheaths his sword and hacks of Peter's arm. (Jesus calls several more times, Peter gradually loses all his limbs). Finally, the guard takes pity on Peter and carries him to the foot of the cross. 'My Lord,' he says. 'What is so important that you would risk this man's life to tell it?' Jesus looks down and says: 'I can see my house from here.'
I think that joke is shit. Most of the people I know find it funny.
