I love how Karl's crazy fantasies aylaws start with a grain of truth. I remember watching a programme a few years ago on Animal Planet or NatGeo where the US navy were actually training dolphins to be suicide bombers. The dolphins had a large red button on their nose and when they pressed the button against the submarine they got a reward..but in real life the button would be a detonator blowing up the dolphin and the sub. The US Navy say that have since abandoned the programme
