We've all heard the saying: If it walks like a duck, swims like a duck, and quacks like a duck, it's probably wearing a suicide vest. No? Well, maybe it doesn't go exactly like that. But it could now, thanks to members of the online image-based bulletin board 4Chan, who've been trolling the terrorist group by superimposing rubber duck heads on to images of ISIS fighters.

According to the Guardian, it all began when one brilliant 4Chan user posted this: “How about castrating the image of Isis by replacing the faces on ALL the propaganda photos with bath ducks?” Pure. Fucking. Genius.

Operation "Allahu Quackbar" has since taken the Internet by storm. Of course, a bunch of silly memes aren't as effective as, say, a laser-guided GBU-28 missile, but considering ISIS relies heavily on slick propaganda videos and images to recruit naive youngsters from around the world, changing the way the terrorist organization is perceived is crucial to disrupting ISIS's enrollment efforts. Perhaps the next time some lonely 18-year-old virgin from the suburbs of Michigan is considering buying a plane ticket to Syria, he'll stumble across these photos and think, "Hey, maybe joining the Islamic State isn't the best way to overcompensate for my micropenis after all!"

That's probably wishful thinking, but take a look at these pictures. Share them. And if you have a few minutes to spare, make your own and upload it here.
