I took the below screenshot just a few moments ago, about 11:26 a.m. (Rome time) on Tuesday, April 21, 2015. How long the front page of cnn.com will remain like this, I do not know. Take a look and see if you notice anything glaringly wrong:

For those who might not know, Christians have only existed for almost 2,000 years now, hardly 4,000 years as the headline reads. Incidentally, the headline does not transfer over into the actual story, which has a different headline.
