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 f**king blanket.'  

After a moment of silence, ......................he farted.
