Most embarrassing thing you've witnessed on a cruise

My good friend went on a cruise with me for a graduation present. We shared a room with two beds though it was a small cabin, but with a deck. One day I came back from swimming and saw him panicking on the deck. He had gone out there to sunbathe in his birthday suit and the door locked behind him. The towel was swept away by the breeze and he was standing there buck naked. I guess he had been out there for a while since he was beet red all over. I helped him inside and applied aloe all over him from head to his toes. He was thankful and when he felt better gave my bare feet a nice massage
