I got the full series for Xmas this year and watch a few episodes every few weeks. My favorite one so far is when Mike is testing a sonar system and to prove its accuracy to some fisherman he spots a 6 or 7 foot shark. Mike dives down to bring it up. The shark the diver nets is about 11/2 ft maybe compared to the divers arm. When Mike is back on the boat, with the fish along side the boat where the camera can't see, he points over the side and says "there, that sharks 6 or 7 feet long don't you think". Still fun to watch. Got to go, Flipper is coming on.
