Monday's Comedy Central Roast of Justin Bieber was proof you shouldn't dish it out if you can't take it.
The panel of comedians, rappers and Martha Stewart got just as eviscerated as the guest of honor, providing some of the largest laughs of the night.
But surprisingly, Bieber was the one doling out some of the funniest quips and harshest truths (guess his money can afford a solid team of comedy writers).
And since Justin got the last laugh, we can all keep calm and beliebe on.
