"Grandma Lorraine sighed again. 'About thirty years ago Marty decided to prove he wasn't chicken — and he ended up in an automobile accident.' / Thirty years ago? Jennifer frowned. That would be back in 1985, wouldn't it? But nothing like that had happened to Marty — at least, it hadn't happened yet. / 'Oh, you mean with the Rolls-Royce?' Marlene asked matter-of-factly. 'You're garbled on that, Grandma. That wasn't Dad's fault. He told me so himself.' "
On page 73 of the novelization (see Quote above), a misprint — namely, the omission of a comma — resulted in Marlene's line 'You're garbled on that, Grandma' reading the grammatically incorrect 'You're garbled on that Grandma' instead. This error has been corrected here.
