(Hawkeye is raging at Potter for swearing Klinger back into the army)
Potter: Look, I had no choice. Klinger came in here all fired up and said that if I didn't swear him in, he'd drive to ICORPS and find someone who would.
Hawkeye: WHAT'S THE DIFFERENCE?! ALL YOU DID WAS SAVE HIM A TRIP!
Potter: This difference is that I had a chance to hear those immortal words "I, Maxwell Klinger, being of sound mind, will faithfully execute the office of soldier, and will to the best of my ability preserve..."
Hawkeye: Wait a minute, wait a minute. "Office of soldier?" That doesn't sound like the oath I took.
Potter: That's because you've never been elected President to the US of A.
Potter: Klinger didn't say exactly what oath he wanted. I figured he wouldn't know the difference, and it bought us a little time.
