I'm going to see Final Fantasy later this month and the two tickets are pinned to the notice board in my mum's flat together with 2 bits of paper, all held by the same pin.

Twice now, one of the tickets has mysteriously appeared on the floor in the kitchen doorway, in exactly the same place despite the fact everything else is still pinned there, and the ticket has a hole where it has been pinned (so it can't have come off by not being attached properly), and it hasn't been ripped to the edge and fallen off.

Mega-creepy.
