Though a bit troubling in spots, This is the End is still a pretty damn good bro movie with lots of laffs. AND! As I spent a little too much time on in my review, the most glorious moment of all is when Rihanna slaps the ever-loving shit out of Michael Cera. I called it a "slap for the ages" and you can now see that slap in action in GIF form after the jump. (Note: The lack of sound takes some of the power away... but look at that wind up and follow through! I hope they shot that scene 17 times.)
