From DPA, with thanks to Mike:
Athens: An Orthodox Christian and a Muslim man who were travelling to Germany were forcibly put on separate flights after they began fighting over their religious beliefs at the international airport here, reports said on Thursday.
The men, bound for a flight to Frankfurt, began arguing on the bus as they were being transferred from the terminal to the plane.
According to reports, the two men started fighting over who was the more religious of the two when the Muslim man, fed up with being attacked, suddenly exclaimed that he was going to blow up everyone on the plane.
Well, that certainly proves that he was the more religious of the two.
