One day Mr. Smith, the president of a large corporation, called his vice-president, Dave, into his office and said,
"We're making some cutbacks, so either Jack or Barbara will have to be laid off."
Dave looked at Mr. Smith and said,
"Barbara is my best worker, but Jack has a wife and three kids. I don't know whom to fire."
The next morning Dave waited for his employees to arrive. Barbara was the first to come in, so Dave said,
"Barbara, I've got a problem. You see, I've got to lay you or Jack off and I don't know what to do?"
Barbara replied,
"You'd better jack off. I've got a headache."
