A man and a woman who had never met before, but 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 bunk 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 so kind as
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 to each other.'

'Wow! That's a great idea!' he exclaimed.

'Good,' she replied. 'Get your own f***ing blanket.'

After a moment of silence, he farted.
