In a top secret document that I was given access to, I read that the US Gvt is about to announce new regulations on the sale of shrimp caught in the oil spill zone. Customarily, shrimp are sold by count. In the new regulations shrimp will be sold by weight. The US Gvt will recommend 5w-20 shrimp for consumption in the cooler climates, and the 10w-40 for the warmer climates. Straight 30w is recommended for Carribean resorts.
