Tuesday's Wall Street Journal has an article about the Dutch takeover
of JFK airport's International Arrivals building. The Dutch have some
interesting ideas on how to clean it up: 
In Amsterdam, the tile under Schiphol's urinals would pass inspection
in an operating room. But nobody notices. What everybody does notice
is that each urinal has a fly in it. Look harder, and the fly turns
into the black outline of a fly, etched into the porcelain. 
"It improves the aim," says Aad Kieboom. "If a man sees a fly, he aims
at it." Mr. Kieboom, an economist, directs Schiphol's own building
expansion. His staff conducted fly-in-urinal trials and found that
etchings reduce spillage by 80%. 
"We will put flies in the urinals -- yes," Jan Jansen says in a back
office at the Arrivals Building. He is the new Dutch general manager,
the boss as of noon today. "It gives a guy something to think about.
That's the perfect example of process control." 
His New York public relations attendant titters. "Fine, laugh at me,"
Mr. Jansen says. "It works." 

My twin sister and I had been out on our first double date. I immediately 
walked in the house after the date, but my sister stayed outside to kiss 
her date goodnight. My mom was curious to see what they were doing. In 
order to see, she had to step on the toilet lid in the bathroom to see out 
the window. It was dark and she failed to close the lid so she slipped 
into the toilet. She was really embarrassed when she came into the front 
room with wet feet and had to explain why.

My wife and I were watching a show on The Learning Channel titled, "A 
Dog's World." One segment focused on dogs practice of urinating everywhere 
to define who they are and whose territory it is, among many other things.
"Basically," the narrator said, "dogs are leaving each other messages."
I looked at my wife and said, "So I guess we could call it p-mail."
