Magnum, P.I., Season 6

Magnum:
[narrating] When I was 14 years old, my grandfather took me crabbing. Now, crabbing's a lot different from trout fishing. See, you tie the bait on the line, you drop it in the water, and when you feel the crab crawl up on the bait, and start nibbling away, you have to slowly raise the line to the surface and then net him as fast as you can. The only trouble is, by the time you can see the crab… he can see you. And nine times out of ten, he'll scuttle right back off that bait and disappear into the ocean. Now I guess that's what I always liked about it, the crab had as good a chance of a free meal as you did. But the best thing about crabbing, was that it taught you patience, concentration, and the second sense of when the time was right to sit, and wait it out.
