A man and a woman who had never met before, but who were both married to other people, found themselves assigned to the same sleeping room on a trans-continental train. Though initially embarrassed and uneasy over sharing a room, they were both very tired and fell asleep quickly, he in the upper berth and she in the lower. At 1:00 AM, the man leaned down and gently woke the woman saying:

- Ma’am, I’m sorry to bother you, but would you be willing to reach into the closet to get me a second blanket? I’m awfully cold…

- I have a better idea, she replied. Just for tonight, let’s pretend that we’re married.

- Wow! That’s a great idea!, he exclaimed.

- Good, she replied. Get your own fucking blanket!

After a moment of silence, … he farted.
