Hey, it's not a bulletproof source, but they've been right before. I think it could be unbelievable, if you use your imagination.
EDIT: don't use your imagination. *shudder*
The original tweet from Johnson says "he's going to need a bigger basement," which is clearly a reference to the line from Jaws, "we're going to need a bigger boat." I don't think I'm going out on a limb to say that, in keeping with all the conjecture posted here tonight, I think we can all agree that the most likely explanation involves sex with an underage shark.
I can't find a link but didn't Ford say something along the lines of "I have an idea of what's on the tape and it ain't pretty"? Or did I imagine that?
Perhaps the video features Ford and his buddies playing pool in a tiny room with their cues hitting the walls when they shoot. Hence the "he's going to need a bigger basement" comment.
I should also add that I heard and posted here about the sex angle before other sources came out talking about it. I like those odds.
