Fish: Here ya go.

Shark: This is the same license twice!

Fish: No, there's two. Look, there's the serial numbers.

Shark: Where?

Fish: Right there, top of the page. This one's number 1, and that one's number 2.

Shark: Oh. Aren't those awfully low numbers?

Fish: We were early adopters. Competitive advantage.

Shark: Ah. Wait, why are they in different corners?

Fish: Security measure. Anti-photocopy technique. That's how you know they're authentic. Defense-in-depth.

Shark: Oh yeah, I remember now. Glad I approved it.
