This comic directly references the Series 6 premiere of DOCTOR WHO’s “The Impossible Astronaut.” Explaining what’s going on here is on par with explaining the “very funny in-joke” you told your best friend who is standing so far outside the jest that’s s/he is ten feet from the fence of ever fully understanding.

We strongly suggest you watch “The Impossible Astronaut“(hopefully the Crackle video will work for you) or read Kyle Anderson’s spoiler heavy review over on The Nerdist.

Hard-core Whovians are laughing their heads off at this. We know because we are One Of Them.
