Kody Brown committed a faux pas on Sunday's episode of Sister Wives, claiming he wants to be "obeyed" by wives Meri, Janelle, Christine and Robyn in response to an incident during the family's stress-filled RV trip to Illinois.
Driving responsibilities turned out to be a source of tension, as at one point, Kody stormed away from the RV after wife Meri insisted he needed more rest before taking the wheel again.
Kody explained of his anger: "You know, I've had two nights in a row where I've been driving all day. Today, we've been fighting the wind all day, and I've had four hours of sleep ... and I was just done.
"I was just ready to melt down because I was too exhausted to sit there and try to delegate -- I wanted to bark orders and have them obeyed."
His wife Christine expressed her discomfort with the phrase.
"I think that word, ‘Obey,’ is in fact a four-letter word," she said. "Kody, I think that we do our best.

"We understand that you get tired. We understand that you get stressed out. You can't just throw out, 'I think you should obey me!' It's kind of like ... well, that's offensive."
Kody countered, "When I’m really grumpy, it’s hard to sit here and try to sell everybody."
The family, who belong to the Apostolic United Brethren Church, later had an emotional response when visiting the location where their faith's founder, Joseph Smith, was killed.
