a man called Dr John C. Lilly as he explained to Calvin and a small group of assembled scientists how he had recently trained a dolphin called Elvar to play fetch with a rubber ring in a unique way – instead of using his nose to catch the toy, Elvar had been taught to use his erect penis. Dolphins can achieve voluntary erections in just three seconds, Lilly told the crowd. By the time he’d thrown the toy ring into the pool, Elvar was able to gain an erection and collect the ring as it dropped to the bottom, returning it to Lilly.
