The giant box in the episode "The Pandorica Opens" on the British Television show Doctor Who.
It is said to be just a fairytale, but a secret alliance between all of the Doctor's enemies plan to trap him in the box to save the universe.
River Song: I'll see you again. When the Pandorica opens.

Doctor: Oh please. The Pandorica is just a fairytale.

Get the Pandorica mug.
A prison, a weapon and a fairytale. Oh, but it's more than a fairytale. No, no... it's real. A giant box that has been searched by every race since the start of time. And it ended with a girl in a museum.
Listen, you lot, you're all whizzing about. It's really very distracting. Could you all just stay still a minute because I AM TALKING! The question of the hour is, who's got the Pandorica? Answer, I do. Next question. Who's coming to take it from me? Come on! Look at me. No plan, no back up, no weapons worth a damn. Oh, and something else. I don't have anything to lose! So, if you're sitting up there in your silly little spaceship, with all your silly little guns, and you've got any plans on taking the Pandorica tonight, just remember who's standing in your way. Remember every black day I ever stopped you, and then, AND THEN, do the smart thing: Let somebody else try first.
