You trying to tell me you didn't hear that shriek? That was something trying to get out of its premature grave, and I don't want to be here when it does. - Phantom of the Paradise (1974)

Quite interesting. Those types of distortions are a really hard thing to understand. And he appears to be very intelligent, precise, and articulate in his speech, but the processing time is slowed way down—I guess that's part of the condition. I hope they were able to help him.

Yes. This must be a rare condition.
