The time has come, as it does every February, to celebrate President's Day. Here is a look back at bits of information about every U.S. president who has served this great country.
* George Washington owned slaves, whom he freed in his will when he died.
* John Adams offered this prayer: "I pray to heaven to bestow the best of blessings on this house and all that hereafter inhabit it. ... May none but the honest and wise men ever rule under this roof." The prayer was later carved in the State Dining Room over the fireplace.
* Thomas Jefferson originated the custom of shaking hands with the president of the United States. Before his term people bowed to the president.
* James Madison was the first president to regularly wear trousers instead of knee breeches.
* In the election of 1820, James Monroe received every electoral vote but one. A New Hampshire delegate wanted George Washington to remain the only president elected unanimously.
* The story goes that John Quincy Adams customarily took a nude early-morning swim in the Potomac River. Anne Royall, the first female U.S. professional journalist, knew of his 5 a.m. swims. After being refused interviews with the president time after time, she went to the river, gathered his clothes and sat on them until she had her interview. Before this, no female had ever interviewed a president.
* Andrew Jackson bought 20 spittoons for the East Room for $12.50 each. Some said it was a great waste of government money while others said it would save the White House rugs.

* James Polk fulfilled all his campaign promises. During his administration, Polk acquired California from Mexico, settled the Oregon dispute, lowered tariffs, established a sub-treasury and retired from office after one term.

* Abigail, wife of Millard Fillmore, arranged for the purchase of the first cooking stove in the White House. The cook couldn't figure out how to work the stove, so the president went to the U.S. Patent Office, read the patent for the stove, and went back to the White House and taught the cook how to use it. Abigail also set up the first White House library and had the first bathtub installed.
* Franklin Pierce gave his 3,319-word inaugural address from memory with absolutely no notes.
* When James Buchanan left the White House, he left a note for his successor, Abraham Lincoln: "My dear sir, if you are as happy on entering the White House as I on leaving, you are a happy man indeed."

* President Andrew Johnson was buried wrapped in a U.S. flag and with his well-worn copy of the Constitution under his head.
