An executive was in quandary. He had to get rid of one of his staff.
He had narrowed it down to one of two people, Debra or Jack. It would
be a hard decision to make, as they were both equally qualified and both
did excellent work. He finally decided that in the morning whichever
one used the water cooler first would have to go.
Debra came in the next morning, hugely hungover after partying all
night.   She went to the cooler to get some water to take an aspirin
and the executive approached her and said: "Debra, I've never done 
this before, but I have to lay you or Jack off."   
Debra replied: "Could you jack off, I have a terrible headache."
