Oh, I dunno. Being a scuba diver, it might be cool to have sunken TV Set as part of an aquarium. Sort of like a man made reef, with the fish swimming about the tubes, transformers, 'lytics, etc like some shipwreck. Of course, the cad plating wouldn't do 'em much good.
Of course, you'd have to have the TV INSIDE the tank, and that would take a big tank. I used to have a 180 gallon, six foot wide by two foot high salt water tank, built into a wall. I got sick of that after 10 years, ripped it out, blanked over the opening, and put a 50" Pioneer Elite Plasma, with all the Home Theater Electronics hidden behind. I got sick and tired of 100 buck tropical fish kicking the bucket.
Geeeze, that's a pretty strange scenario. I guess I need a cup of tea.
