Due South: "The Bounty Hunter"

In Season 3, Episode 6, Constable Benton Fraser appears at the Chicago Police Dept. one morning and discovers the squad has decided to go on strike. Or, rather, catch the "Blue Flu."  But not before an attractive bounty hunter, of the female variety arrives at the station with her three kids. 

The cops soon vacate leaving the police station deserted. Fraser takes pity on her, allowing Janet Morse (played by Wendy Crewson) along with her two girls and one boy to stay at the station.

Being the gentleman and protector that he is, Fraser spends the night at the station too rather than returning to his apartment. He sleeps in the hall outside of the room Janet and the kids are staying. He certainly can not wrinkle his Royal Canadian Mounted Police uniform so, like at home, he strips and sleeps in his bright red union suit.

But, oh man, he is woken up the following morning by his company commander and is he is ever in trouble. He jumps up and stands at attention in his long underwear and gets quite a "dressing down."

He is even in more trouble when Bounty Hunter Janet comes out of her room in her night clothes with a toothbrush. Boy oh boy!

Fraser is ordered to follow the commander into to her office for more words....

He is finally allowed to about face and leave her office still in his combinations to retain his uniform and get properly dressed.
