The Incredible 2-Headed Transplant1971

Danny:
[as the 2 headed monster wakes up] Daddy. Daddy.

Cass:
Whatta you know. He can talk.

Danny:
Who are you?

Cass:
I'm your brother.

Danny:
I don't have a, a brother.

Cass:
You do now. I don't like it any better. But until we can do something about it, I'm running this monster, understand?

Danny:
Uh, my neck hurts.

Cass:
My neck hurts, stupid. Don't you see what these maniacs had done to us?

Danny:
Stop jerking around. You and I are now one, dummy. Let's stand up. I'll show you.

Cass:
[as the monster gets up and starts walking for the first time] Aaaagh! I gotta teach the moron to walk.
