A Guy was staying in a fancy hotel and was enjoying the pool when the manager told him quite bluntly to get out. When asked for the reason, the manager said, "Because you peed in the pool."
"Well," replied the swimmer, "lots of people do that."
"True," answered the manager, "but you did it from the diving board."

Traffic signal

In 1909, Thomas M. Flaherty filed for a U.S. patent, with an idea for a "Signal for Crossings" This was the first U.S. application for a traffic signal design, later issued as No. 991,964 on 9 May 1911. His signal used a large horizontal arrow pivoted on a post, which turned to indicate the right of way direction. It could be activated by an electric solenoid by a policeman beside the road. Although filed first, it was not the first patent actually issued for a traffic signal. Ernest E. Sirrine filed a different design seven months after Flaherty, but his patent was issued earlier, and thus he held the first U.S. patent for a "Street Traffic System" (No. 976,939 on 29 Nov 1910).
