Two strangers, a man and a woman, are sharing a sleeper cab on an overnight train

At around midnight, as they are both trying to fall asleep, the man says to the woman:

"Excuse me ma'am, but it's really cold, would you mind passing me one of the extra blankets on the table beside you?"

The woman answers:

"I'll tell you what, I'm also feeling really cold, for one night, why don't pretend we are married?"

The man, taken aback but enthusiastic replies:

"Yeah of course!"

And so the woman says:

"Good. Then fucking get it yourself you lazy ass."
