Freshman Orientation and the Inventor of the Zipper - S4-E6
Plot hole: Memaw gets a call from Dr. Sturgis saying that he has moved to Waxahatchie and would she please call him back. He does not say the new phone number, and this was well before cell phones were in widespread use by the general public, so it could only be a land line. Memaw calls him back, although she could not know the number.

Suggested correction: Memaw could have caller ID, or she could have called information.
Caller ID was first available in December 1988, and it's unlikely that Memaw would have it that early. The story takes place before that time. It is possible that she called information, but when did she do it?
