About "Bob"[]
A traveling salesman for a U.S. novelty company, Bob visits his father-in-law, Col. Potter, at the 4077th. They talk about how, initially, they didn't get along, but now they're fast friends. Bobby even calls Potter "Pop."
When a call from a hotel in Tokyo where Bob, who was there on a business trip, arrives at the 4077th for a Mr. Bob Wilson that "Mrs. Wilson" left a nightgown in the hotel room which he was staying in, it causes Col. Potter to fume. Later that night, Col. Potter, after talking about his son-in-law's transgression to Father Mulcahy, calls his daughter, prepared to tell her the truth. But something stops him from doing so, and he pretends the call was just to say hello.
The next morning, as Bob prepares to leave, things still awkward between him and Col. Potter. But before he goes, Potter reveals he knows the truth about his affair with another woman in Tokyo, but in a surprising way - he tells him about one time when he "slipped up" and was unfaithful to Mildred, admitting that for a week afterward, he felt so bad he couldn't look her in the eye, and could never live with that kind of guilt again.
Bob comes clean, at first offering excuses, but then admitting that he knew what he was doing, even though he knew it was wrong. He promises it'll never happen again, and says that he truly loves his wife and son, and would never want to do anything to hurt them.
Potter accepts this, even admitting that he had called his daughter, prepared to tell her everything, and came very close to tearing Bob limb from limb, but decided not to do either, saying he decided "Why screw up three people's lives over one slip-up?", also going on to say, that he hopes that Bob, an otherwise faithful, loyal husband and family man, would always be a part of his family.
