"Fish on!"
Those two magic words immediately change the tempo aboard a fishing boat.
All wisecracking and kibitzing cease and everyone's attention turns to the fishing pole arching over against the weight of a fish tugging the line taut. As the lucky angler reels and reels, anticipation builds until the first flash of a fish disturbs the still surface of the water. If all goes well, someone will thrust out a net, capture the crafty creature and bring it aboard.
