Admiral Al Calavicci:
Sam! Sam! Listen to me! Sam! I got to reach you, Sam! Sam, what are the four fundamental forces of interactions in quantum physics? Sam. Sam, explain the Pauli exclusion principle. Sam, what is supersymmetry, and how does it apply...? This is never gonna work. It's all happening again. It's November 22, 1963 and it's all happening again! Sam! Sam! It's November 22, 1963! Sam, and your dad is still alive! He's teaching you to drive a tractor, Sam. It's-, it's Elkridge, Indiana. You're ten years old and your dad is teaching you to drive a tractor. At this very moment, your dad is still alive, and he's teaching you to drive a tractor, Sam! On the farm in Indiana! He's still alive!

Sam:
Dad.
