Okay, right off the bat: this isn't really a raygun. I'm not going to tell you otherwise, even though that would be so easy.

It's just an incredible simulation of a raygun, secure in its incredible simulation of a spaceperson's harness, printed on a completely real but no less incredible shirt.

But although you and I know that, we're not going to tell anybody, are we?

Let them believe that this raygun proves you're a swashbuckling corsair from the retro future. Why not?

At the least provocation, you're likely to draw your raygun and start blasting. This is what we call commanding respect.

Although, you know, sometimes it's not exactly respect. But we make do with what we have, right?
