DOCTOR

The patient here has been suffering from a trauma, which we think can be successfully treated by electric shock.

Hello, Billy.

BILLY PILGRIM

Hello.

DOCTOR

We've prescribed a series of twelve and we're up to number seven.

The patient was a prisoner of war in Dresden when it was bombed. He claims that well over 100,000 people were burned to death in the fire. Worse than Hiroshima.

And since Billy was actually there, it's natural enough to assume that this has had a contributing effect on his present condition.

From the 1972 screenplay adaptation of Kurt Vonnegut Slaughterhouse-Five.

Earlier references to ECT here, here, and here.

A reference to John Bunyan's 1678 Pilgrim's Progress here.
