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.
