Marty McFly: Doc, you don't just walk into a store and buy plutonium. Did you rip that off?
Dr. Emmett Brown: Shhhhhh. Of course. From a group of Libyan nationalists. They wanted me to build them a bomb, so I took their plutonium and in turn, gave them a shoddy bomb-casing full of used pinball machine parts! Come on! Let's get you a radiation suit. We must prepare to reload.

Marty McFly: All right, give me a Pepsi Free.
Lou: You want a Pepsi, pal, you're gonna pay for it!
