A vendor addresses a meeting, "If you buy our system it will pay for itself in three years." Dilbert turns to the vendor and asks, "Approximately how much does it cost?" The vendor responds, "It's hard to say. It depends on many factors." Dilbert says, "Fine. Just tell me how much money it will save annually." The vendor replies, "You'll save $10,000 per year." Dilbert says, "Well then, if it pays for itself in three years, it must cost about $30,000" Dilbert continues, "That was a little trick I call "math." Dilbert continues, "Oops. Now I'm not emotionally invested." Asok pats Dilbert on the back and says, "Your vendor tauntage is quite excellent today."
