General Waverly has told the driver to take "the shortcut" route to take his replacement back to base:
Joe: "That's not the way back to base!"
Waverly: "Joe, you know that, and I know that, but the new General doesn't know it. Or he won't for about an hour and a half."
Joe: "That Sergeant'll be a private in the morning!"
Waverly: "Yes. Isn't he lucky?"
