The boss had to fire somebody

The boss had to fire somebody, and he narrowed it down to one of
two people:
Mary or Jack. It was an impossible decision because they were both decent
workers. Rather than flip a coin, he decided he would fire the first one
who used the water cooler the next morning.

Mary came in the next morning with a horrible hangover after partying all
night. She went to the cooler to take an aspirin. The boss approached her
and said, "Mary, I've never done this before, but I
either have to lay you or Jack off."

"Could you jack off?" she said. "I feel like shit this morning.”
