Mr. Smith owned a small business.  He had two employees, Sarah and
Jack.  They were both extremely good employees - always willing to
work overtime and chip in where needed.  Mr. Smith was looking over
his books one day and decided that he  wasn't  making enough money to
warrant two employees and he would have to lay one off.  But both
Sarah and Jack were such good workers he was having trouble finding a
fair way to do it.
He decided that he  would  watch them work and the first one to take a
break would be the one he would lay off.  So, he sits in his office
and watches them work.  Suddenly,  Sarah gets a terrible headache and
needs to take an aspirin.  She gets the aspirin out of her purse and
goes to the water cooler to get something to wash it down with.  Mr.
Smith follows her to the water cooler, taps her on the shoulder and
says, "Sarah, I'm going to have to lay you or Jack off."  Sarah  says,
"Can you jack off - I have a headache."
