A man and a woman, who had never met before but were both married to other people, found themselves assigned to the same sleeping cabin 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 bunk and she in the lower bunk.
A 1am the man leaned down and gently woke the woman saying "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 bloody blanket!"
After a moment of silence, he farted.

Pardon me, but I think you'll find that's a shovel. See you next Tuesday!
