It's possible you're thinking of:
* A book about Bob Andy Kaufman: Perhaps it's a biography or a collection of his work. If this is the case, Jack Bristow wouldn't be mentioned unless there's a specific connection to the book's subject.
* A book with a similar title: Maybe you're misremembering the title or the author. It's possible a book with a similar name mentions Jack Bristow, but it's impossible to say without more information.
To help me figure out what you're looking for, please tell me:
* What is the full title of the book?
* Who is the author of the book?
* What is the book about?
Once I have this information, I can give you a better answer.
