What is the ninja centerfold?

Oh, dude, the ninja centerfold? That's like the most secretive magazine spread ever, where ninjas strike a pose in their stealthy outfits while flipping through the pages without making a sound. It's like the Playboy of the ninja world, but instead of bunnies, you get black-clad warriors ready to kick butt. Just make sure you don't try to sneak a peek, or you might end up with a shuriken in your coffee.
