dilbert: i worked all weekend to get this done for you by the deadline.
boss: thanks, but i won't need it for another two weeks.
dilbert: then...why did you tell me the deadline was today?
boss: i built some cushion into the schedule.
dilbert: you mean, you lied to me about the real deadline. in other words, you don't trust me, you are a liar, and i should never believe you again.
boss: but you didn't miss the deadline!
dilbert: okay, well, at least my input is critical to our success.
boss: i might have exaggerated that.
