It’s giant news when the world’s largest quick-service seafood chain introduces its biggest shrimp ever. Long John Silver’s is introducing the new, nearly-half-foot-long Giant Shrimp to America this week. Long John Silver’s Giant Shrimp have been in the news since mid-January, when company President Steve Davis sent a letter to NASA Administrator Sean O’Keefe, offering to give America free Giant Shrimp if NASA’s Mars Rover finds conclusive evidence of an ocean on Mars by Feb. 29. The giveaway would take place on March 15, between 2 p.m. and 5 p.m.
