Here's a bit of a mix-up:
When George and Jerry go into Kimbrough's office, and they shake hands with the executives, George says: "Hello Stu!" and Stu replies, "You remember Jay Crespie?"
BUT in the FIRST episode of this season (901 - The Butter Shave), Kenny Bania is approached by two executives from NBC who introduce themselves as Jay Shermack and Stu Crespie! Mixed up, jumbled up names!
