An office manager had been told by his head office to 'downsize' his staff and he'd worried hard and long and narrowed the choice down to two members of his team, Alice, who was OK at her job but was a bit of a 'party animal' and Jack who was also OK at the job but was a bit of a chauvanist pig.
The manager could not decide so he decided to give the two people the option to 'resign'
On the day in question he arrived at work and found Alice at the coffee machine looking a little 'worse for wear' and he said to her, "Alice! I'm sorry but I'm going to have to lay you or Jack off"
Alice replies, "I've got a bitch of a hangover! Would you mind jacking off this once"
