It's whaling season in the Antarctic Ocean, which means the rotten-butter-wielding activists at Sea Shepherd were busy making life miserable for the Japanese whaler Yushin Maru No. 2 today. Activists hurled paint and butyric acid—found in the aforementioned rotten butter—at the ship, as well as ropes designed to foul its rudder and propellers.
