In the second episode of Men in Kilts, Sam Heughan and Graham McTavish engage in a competition of many Scottish sports, including rugby, golf, and surfing. And then one of them swims buck-naked into the North Atlantic Ocean. But wait, there’s more! (There’s not, I just wanted to write, “But.”) The Outlander co-stars decide on a friendly sports competition and bet at the beginning of the episode, where the loser must skinny dip in the ocean. It’s very cold in Scotland, btw.
