Greatest Facts Contest Extended Through Sunday

We're on the hunt for the Greatest Facts in American History, and we're giving away $1000 in prizes in the hopes you'll help us find it!
Did you know that:
- Growing up, George Washington celebrated his birthdate as February 11, 1733. But when British colonies adopted the Gregorian calendar in 1752, his birthdate was recalculated to the 22nd?
- Or that until coffee gained popularity, beer was the breakfast beverage of choice in most urban areas of the United States? (Not that we’re endorsing that!)
- Or that Woodrow Wilson never owned a dog, but he and his wife kept a flock of White House sheep as pets... and natural lawn mowers!
Those are just a few of the facts we learned while researching our new US History book. But we’re guessing you’ve got something even better up your sleeve. All you have to do is share one fact on the form here, and you could win one of ten $100 shopping sprees to the mental_floss store. (Note: only facts submitted through the form will be considered.) But remember, one entry per person.
Contest ends Friday, Oct 15 Sunday, Oct 17, so be sure to get your entry in soon!
