Summary
- B.J. cheated on wife Peg during “Hanky Panky” episode of MASH.
- This storyline is controversial, with some fans finding B.J.’s actions completely out of character.
- Farrell’s B.J. had another close call with temptation in season 8, but ultimately reaffirmed his love for his wife.

When Mike Farrell’s B.J. Hunnicut was introduced in season 4 following Wayne Rogers’ abrupt exit as Trapper, the two characters shared much in common. Over time, Hunnicut became a distinct character from Trapper, largely due to Farrell finding his feet in the role. Whereas Trapper was married but had no problems having affairs while away from home, Hunnicut deeply loved his wife Peg and refused to sleep around. He and Hawkeye (Alan Alda) still got up to childish antics to relieve tension, but Hunnicut was definitely the more mature of the duo.
Yes, B.J. Cheated On His Wife Peg In MASH’s “Hanky Panky”
B.J. fell off “the fidelity wagon” during season 5

MASH ran for 11 seasons, so few potential storytelling stones were left unturned. It was only natural at some point B.J.’s loyalty would be tested by the writers, which arrived with season 5’s “Hanky Panky.” This shows Hunnicut comforting a nurse named Carrie (Ann Sweeny) after she receives a letter from her husband telling her their marriage is over. During his efforts to provide a friendly ear, the two kiss, and B.J. spends the night in her tent.
“Hanky Panky” never outright states what happened, but it’s obvious B.J. cheated on his wife during his night with Carrie. Some MASH fans have argued there’s room for interpretation, but considering how guilt-ridden Hunnicut is when he confesses to Hawkeye, it’s clear he and Carrie slept together. He tells his best friend he “fell off the fidelity wagon” and is mystified that he could have been unfaithful.
Hawkeye talks him out of confessing in a letter to Peg, and after a period of avoiding Carrie, the two also have a heart-to-heart about their night together. MASH’s “Hanky Panky” may not paint Hunnicut in a great light, but it makes it clear the guilt will stick with him for some time. While a character like Frank might justify being unfaithful to his spouse whilst overseas, Hunnicut is definitely not that type of man.
Why B.J.’s Infidelity Was Controversial With MASH’s Fanbase
Hunnicut’s night with Carrie still inspires debate

MASH ran for 256 episodes, and like any longer-running series, there were plenty of dud outings. There are also episodes devotees like to ignore, such as season 4’s “Hawkeye,” where Alan Alda’s surgeon has to talk incessantly for 20 minutes to keep himself awake following a head injury. Some MASH fans like to pretend “Hanky Panky” didn’t happen since they hate the idea of Hunnicut cheating on Peg.

This is a shame, since “Hanky Panky” is a very good episode. It’s a showcase for Farrell as a performer, and the unexpected romance he forms with Carrie is a tender one. It’s a surprisingly complex outing, exploring the effect that being overseas in a warzone for prolonged periods can have on a marriage. Carrie thought hers was ironclad until she received her husband’s letter, while even Hunnicut admits that despite the guilt he feels, he’s still worried about his feelings for Carrie going deeper.
The two close out this MASH episode as friends, and in keeping with the show’s unfortunate tradition with nurse characters, Carrie is never seen again. B.J.’s infidelity might have disappointed his fans, but that doesn’t mean “Hanky Panky” should be ignored or overlooked either. If anything, it made him a more complex character.
