So I was watching The Impossible Astronaut & Day of The Moon
and decided to pull a prank on my brother.
He sees the Doctor Who episodes a few days-weeks after I do. I’ve decided to exploit this for my own amusement.
While he sleeps, I’m going to draw those black marks up and down his arms and hands, and on my own face as well. He’ll wake up not knowing what they are, seeing them on his own arms and my face. I, of course, will pretend not to know the marks are there. He will have no idea where they came from, as though he's forgotten.
And in a few weeks, when he has actually forgotten about the marks, we’ll watch those episodes. He’ll be freaked the hell out and I’ll sit back and pretend I’m not an evil genius.
