Here's one I overheard that left me slack-jawed:
Some guy: (in a very loud voice) "Have you noticed that the whole world uses the same calendar to mark the year? Everyone refers to the current year as so-and-so AD, which stands for anno Domini, "the year of our lord, Jesus Christ". Why don't the Chinese and the Muslims have their own calendars?"
Listener, an Anglican priest: "That's because Christendom has dominated the world politically and economically for centuries."
Some guy: "Makes you think, though, doesn't it?" (leaves the building with a smug look on his face).
Priest: (what the fuck?)
