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 transcontinental 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 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 damn blanket!
After a moment of silence........................he farted.

LOL
