When iOS 7 launched, Conan showed us all how to go about installing it. But as one eagle-eyed viewer has since pointed out, he screwed up big time—by trying to install the OS on an iPhone 3GS, which doesn't even support it.
In fact, it's the first time a viewer has successfully challenged Conan on the Fan Corrections segment of his show. But, as you might expect, Conan's reaction is preeeeeetty amusing. Take a watch. [Team Coco]
