Dave got called to the directors office...
"Dave we have to make some cutbacks, either Jack or Sarah has to be laid off"
"This is really hard" Dave says "Sarah is my best worker but Jack has 3 kids to support"
The director gives him a day to think about it.
Later that day he calls Sara to his office "Sarah I've got a real problem. I've got the either lay you or Jack off"
Sarah thinks for a moment "you should probably jack off. I'm on my period"
