Dr. Emmett Brown: What's the biggest problem with the new DeLorean?
Martin Seamus 'Marty' McFly: Fifteen on the highway, twelve in the city?
Dr. Emmett Brown: False! If you park it on the street, it's bound to get ripped off.
Martin Seamus 'Marty' McFly: Well sure, because its a time machine.
Dr. Emmett Brown: Cause it's a DeLorean! These things are collectors' items.
Verne Newton Brown: Dad, Jules said he could use the computer, but now he won't let me.
Jules Erastosthenes Brown: But father, I have almost completed my calculations, and the delay would be intolerable! I'm computing the logarithmic equivalence of the atomic weight of certain isotopes found in the lampanide series of rare earth elements.
Dr. Emmett Brown: Again?
Verne Newton Brown: I'm trying to beat my all time score on 'The Legend of Bruno'.
Dr. Emmett Brown: Great soups I'm baffled! On the one hand Jules is on the eternal search for knowledge, on the other hand Verne is developing the hand-eye coordination which will come in handy in the world of the future.
