As we've said time080p Archivestime again, Elon Musk is serious about boring.

The CEO of Tesla and SpaceX (who, since recently, also has "Tunnels" listed in his Twitter description) has posted a photo of a hat with a sign "The Boring Company."

The hat, a flimsy black baseball cap -- you know, the type your granddad probably wears -- is exactly what we'd expect from Musk at this point, since he made several puns about "boring" tunnels.

If you're wondering what the hell are we talking about and whether this is the same Musk who aims to send people to the Moon and Mars, the answers are "we're not quite sure yet" and "yes, it's the same Musk."

In December 2016, Musk complained (on Twitter) about Los Angeles traffic, claiming (jokingly at the time, or so it appeared) about building a "tunnel boring machine and just start digging."

As time went on, Musk appeared more and more serious about the idea, eventually proclaiming that he's "actually going to do this" and posting images of what appears to be a tunnel in progress.

But honestly, it's all child's play compared to the hat. Now that there's a "Boring Company" hat, the entire thing is officially official. Musk did not share an official way to buy these beauties, but he did reply to one person on Twitter saying he'll send him one, so you can try your luck there.
