Water?

Two fish met in a stream.

"How've you been?" asks one.

"You won't believe what happened to me." replied the other. "I had a truly amazing experience. I saw a tasty tidbit floating overhead so I snapped it up. The next thing I know, I'm in this whole other world, a piece of hard, shiny stuff hooked in my mouth, hanging on a string, and I can't breath! I'm suffocating! Then this giant something grabs me, takes the hard shiny thing out of my mouth, and throws me back in the water."

"Water? What water? What are you talking about?" asks the first fish.
