Me: "Hey, some internet nerds over at this Trekmovie website are speculating that the bad guy in the new Trek movie is going to be Garth of Izar."
Casual fan: "Garth of who?"
Me: "They also think he might be Gary Mitchell."
Casual fan: "Who the fuck is Gary Mitchell?"
Me: "They're also saying that he might be Khan."
Casual fan: "Oh, you mean that guy in The Wrath of Khan where Spock dies?"
Casual fan: "Awesome! I loved the Wrath of Khan! That was the only Star Trek movie I ever saw, and it was badass. My butt will be in the theater seat for this new movie then."
