A man and a woman who had never

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 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 berth and she in the lower.

At 1:00 AM, the man leaned down and gently woke the woman saying,

‘Look, 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  blanket.’After a moment of silence, he farted.
