A particularly un-painful disease that causes the infected person to take pitifully long periods of time to complete a seemingly easy task.
Those infected with "The Sceep" should immediately consult a professional dealing with the task at hand. Unfortunately, professional consultation, and treatment of "The Sceep" can be very expensive, and infected persons have been known to just give up caring what anyone thinks about their time-line.
