How many managers does it take to change a light bulb?

1) "I want a detailed memo about this issue till tomorrow's morning."

2) "You were supposed to have changed that light bulb last week!"

3) "We haven't got a policy on that."

4) "I am on my way to a very important meeting, so we'll discuss it some other time."

5) Three. Two to find out if it needs changing, and one to tell an employee to change it.
