This is a little joke from the WordPress developers. I discovered this hidden “feature” two or three weeks ago, during my work on the website. I was trying to revert to a previous revision of an article and start comparing two identical revisions which has obviously no sense. I remember that at this instant, I was making an audio conference with a friend and he get a whole live transcription of the event, quite a bit scary at the very beginning ^^ If you know any other ones, let me know!

Steps to follow:

• Create a new post;
• Give it a title;
• Save it as draft (to avoid publication);
• Page down and click the revision (a date);
• Compare it with itself;
• Enjoy…
