Justin Bieber has been tweeting at Seth Rogen with such regularity in the run-up to his Comedy Central roast later this month that it's kind of becoming a problem. We get it, Biebs. You remember being slighted by Rogen last year and think it would make for some awesome material. But calm down, man.

And, not to put too fine a point on it, but I have a tough time believing Bieber has ever actually taken anything like a man.
