Only Fools and Horses: The Miracle of Peckham - While in the local church, Del Boy witnesses a miracle when he notices that the a statue of the Virgin Mary on the altar appears to be weeping. Within days, reporters and cameramen from all over the world are in Peckham to cover the story when after a few more miracle weeping sessions, the priest realises that the miracles only occur when it is raining. Upon inspecting the church's roof, he finds that all of the lead tiles are missing.
Only Fools: The Miracle of Mumbai - Local people declared a miracle when tears began trickling down the face of a statue of Jesus at the local church. Locals began collecting the holy water and the Church of Our Lady of Velankanni began to promote it as a site of pilgrimage. On inspecting the Church's plumbing, it was discovered that the dripping water was due to clogged drainage pipes behind the wall where the statue stood.
Unlike Del Boy, the man who discovered the dodgy pipework received death threats, was charged with blasphemy and is now seeking exile in Finland as an arrest warrant was issued.
It seems that keeping up the cash flow from the miracle is more important than stopping the sewage flow which caused the miracle. I just hope that nobody is christened in it as i wouldn't want to be the vicar who has to explain to the parents why the water had a faint yellow tinge to it.
