Back to the Future1985

Marty McFly:
So does it run on regular unleaded gasoline?

Dr. Emmett Brown:
Unfortunately no, it needs something with a little more kick - plutonium.

Marty McFly:
Plutonium... wait, are you telling me that this sucker is nuclear?

Dr. Emmett Brown:
No no no, this sucker's electrical, but it requires a nuclear reaction to generate the 1.21 gigawatts of electricity I need.

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 shiny bomb-casing filled with used pinball machine parts.
