Marriage

A man and a woman who had never met before, but were both married to other
people, found themselves assigned to the same sleeping compartment on a
transcontinental train.
Though initially embarrassed and uneasy over it, they were both very tired
and fell asleep quickly... he in the upper bunk and she in the lower.
At 1:00 AM, the man leaned over 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 f#cking blanket."

After a moment of silence, he farted.
