You keep on knocking but you can’t come in. That seems to be the message on the Doctor Who Knock Knock T-Shirt.
The Doctor himself has declared “the assembled hordes of Genghis Khan couldn’t get through that door,” but what about a horde made up of a Cyberman, a Dalek, a Weeping Angel, and the Silence? Chances are still pretty good they won’t be able to get in unless the Doctor wants them in, but you can’t blame the bad guys for trying. Because of that glitchy chameleon circuit, it’s easy to believe you’re just trying to break into a simple police box instead of a powerful ship capable of flying through both time and space.
The Doctor Who Knock Knock T-Shirt is available for $25.99 at RedBubble.com.
