thanks for the link! Dave Barry is worth quoting here:
"Before I took lessons, virtually everything I knew about SCUBA -- aside from the fact that it stands for "self-contained underwater breathing apparatus" -- came from the syndicated television series Sea Hunt. This was a very popular half-hour adventure show that ran from 1958 through 1961 and starred Lloyd Bridges as "Mike Nelson, free-lance undersea investigator."
There were 156 episodes of Sea Hunt, but they all merge together in my mind into one basic plot, namely: Mike Nelson is swimming around, conducting a free-lance underwater investigation when suddenly a bad guy swims up behind him and cuts his air hose. Mike always acted surprised about this, which was pretty funny because in fact he got his air hose cut about as often as the average person burps. You'd think it would have eventually dawned on him that for whatever reason -- possibly related to the Gulf Stream -- the waters around his boat were teeming with air-hose cutters, but old Mike never seemed to catch on.
So the climax of Sea Hunt was always an exciting underwater fight (accompanied by dramatic underwater horn music) in which Mike, his bubbles shooting all over the place, would struggle to get some air into his lungs and subdue the bad guy and get back to the surface and head over to the air-hose store, where he probably got a volume discount. Sea Hunt was great entertainment, but it did not leave you with the concepts of "SCUBA" and "safety" firmly cemented together in your mind. "
