This evening, I'm watching a recording of "Shark Weekend HD" on Discovery HD. The first frame of the program has a big blue screen that reads:

"WARNING

Diving with great white sharks without the protection of a cage is extremely dangerous.

The scenes you are about to see were conducted by professional shark divers with years of experience.

DON'T TRY THIS AT HOME!"

Upon reading this, I have to ask:

1. Is diving with great white's with the protection of a cage not extremely dangerous?
2. Are there people watching who have great white's at home that are thinking of diving with them without the protection of the cage?

It's a mind-boggling to me that people would take a television show like this as an invitation…
