How to make butter

--- 50% of success

To alleviate the perennial shortages of butter, The Politburo of the Communist Party ordered the Soviet scientists to develop a technology for converting shit into butter, and to complete this project on or before the anniversary of the Great October Socialist Revolution. After six months of work, the Politburo demanded an interim progress report. The scientists reported that they had achieved a 50% success. The party requested elaboration. The reply from the Academy of Sciences explained, "One can already spread it, but not yet eat it."
