How do you start a hurricane?

Such is the punchline of an old joke featuring two codgers on a park bench in Miami Beach describing their respective paths to yon park bench, one of whom had a store in the North, destroyed by a fire after which he collected the insurance and retired, the other had a store in Florida, destroyed by a hurricane and then he collected the insurance money and retired… so the man from the North asks the man from Florida… Well, never mind.
WTF does that have to do with… Democratic Senator Tim Johnson of South Dakota entering the hospital with a possible stroke?
I have no idea. None at all. Let us just all pray for Senator Johnson’s speedy recovery.
