Be sure to wish the White House a happy birthday on Sunday.
On Oct. 13, 1792 -- a full 221 years ago this Sunday -- the first cornerstone was put in place for the residence of American presidents from John Adams to Barack Obama.
The first president, George Washington, never lived in the White House -- one of the ten fun facts gathered by the National Constitution Center.
Another fact: That first cornerstone is missing, thanks to some inebriated masons.
"On that fateful day in October 1792, a group of freemasons met at a Georgetown tavern and paraded to the proposed site of the president's mansion. In a ceremony, they placed an inscribed cornerstone to mark the start of the House's construction.
"They then marched to an inn and made a toast to the event. And another, and another. In fact, they made 16 toasts!
"So no one really documented where the stone was.
"President Truman tried to find the stone during the renovation period, but no one has seen it since 1792. One theory is that is imbedded between two stone walls near the Rose Garden."
