Intercourse

The transcript of a conversation overheard late yesterday.

α: #who knocked off Scalia?

β: Is that a new twitter tag?

α: Yes, Conspiracy Boy, I'm starting it.

β: I'm sorry Alpha, but it's not original by you.

α: I haven't seen it. It was an invitation for you to start the conspiracy theory.

β: If it's true, then it's hardly safe saying it.

α: Scalia is the proof.

β: LOL. Tautology much? No. Scalia is the happenstance.
One of us would be the coincidence, and the other would be the proof.
