Each third Monday in February we celebrate Presidents Day (or George Washington's birthday) in the United States. It's meant to be a day when we remember the men who have served as America's leader, and also the nation's military personnel and veterans that make us so proud. 

To commemorate the day, we've compiled some interesting facts about America's Presidents. Enjoy!

- The smallest President was James Madison, at 5'4'' and weighing less than 100 pounds. The heaviest President was William Howard Taft, who weighed 332 pounds when he was elected. After he got stuck in the White House bathtub, Taft ordered a new one installed. The replacement was big enough to hold four average-sized men.

- The tallest President was Abraham Lincoln, at 6'4''.

- The oldest President ever elected was Ronald Reagan, taking office at the age of 69.

- The youngest elected President was John F. Kennedy, who reached the White House at 43. But the youngest President to ever serve was Theodore Roosevelt, who was elected Vice President on a ticket with President William McKinley. After McKinley was assassinated in Buffalo, New York in 1901, Roosevelt assumed the top office at age 42.

- William Taft started the tradition of the presidential "first pitch" of baseball season. Since then, every President but one has opened at least one baseball season during their tenure. The exception: Jimmy Carter.

- Andrew Jackson's pet parrot had to be removed from his funeral service because it wouldn't stop cursing.

- Andrew Johnson never attended a single day of school in his life.

- George Washington, Thomas Jefferson and John Adams were all avid collectors and players of marbles.

- William Henry Harrison died of pneumonia one month to the day after making—in the snow—the longest U.S. presidential inauguration speech on record.

- Ulysses S. Grant once got a $20 speeding ticket for riding his horse too fast.

- James Buchanan was the only president never to marry.

- The first President born a U.S. citizen was Martin Van Buren (in 1782). Van Buren was the first President born after the Declaration of Independence was signed. Barack Obama was the first President born outside the continental United States (he was born in Hawaii).

- Virginia is the birthplace of the greatest number of Presidents. It boasts eight. 

- Richard Nixon was the first President to visit all 50 states.

- George W. Bush was the fourth President elected without winning the popular vote. He shared the distinction with John Quincy Adams, Rutherford B. Hayes and Benjamin Harrison.

- Gerald Ford was the only President to serve who was not elected by U.S. voters either as President or Vice President. In 1973 then-President Richard Nixon appointed Ford Vice President after former Vice President Spiro Agnew resigned. When Nixon resigned from the White House on August 9, 1974 (the only President to do so), Ford became President.

- Barack Obama is left-handed.

- Eight Presidents died in office: W. Harrison, Taylor, Lincoln, Garfield, McKinley, Harding, F. Roosevelt and Kennedy.

- Presidents Adams, Jefferson, and Monroe all died on the 4th of July. Calvin Coolidge was born on that day.

- Only five Presidents in U.S. history have had beards when they moved to the White House -- none in the past century.  

- Dwight D. Eisenhower's dog was banned from the White House after it left a "present" on the floor of the diplomatic reception room.

- George H. W. Bush flew, and survived, 58 combat missions in WWII.

- Theodore Roosevelt once killed a mountain lion with nothing but a knife after it attacked his dogs. Cougars beware!
