1) Barbie has a full name, a family, and a background

Barbie's full name is Barbara Millicent "Barbie" Roberts. The first doll was described as a "Teenage Fashion Model." Her parents' names are George and Margaret Roberts.

2)Mouthing the word "Colorful" looks like mouthing "I love you"

I grew up knowing "Olive oil" looked like "I love you" but I guess this one is true too. Disclaimer: I am not encouraging nor endorsing the use of this phrase to avoid uncomfortable situations in any way, shape, or form; in other words, don't shoot the messenger.

Speaking of which...

3) The phrase, "Don't shoot the messenger" dates back to Greek play writes and Shakespeare

The phrase (in various forms through the ages,) was used in the play Antigone by Sophocles, by Shakespeare in Henry IV, Part II and in Antony and Cleopatra.

4) The first man to survive falling over Niagara Falls in a barrel died of a freak accident

Bobby Leach was the second person to go down Niagara Falls in a barrel, and the first to survive it. Despite surviving the treacherous feat, Bobby ultimately died from slipping and falling on an orange peel (or banana peel, that's up for debate). After slipping, his injured leg became infected; his leg was amputated, and he died from the procedure two months later.

5) Sea otters sleep holding hands

Otters hold hands while they sleep so that they don't float away from each other. Even though humans (usually) don't sleep on floating water, we can take this as a reminder to hold on (figuratively or literally) to those who mean the most to us, and remember to tell them we care. Who knew humans could learn about love and life from otters?

6) Leonardo di Vinci could write with one hand while drawing with the other

They just don't make 'em like they used to, huh? If he doesn't impress you, I don't know what will; it might just be time for you to invent a way to be better.

7) The longest traffic jam in history lasted for 12 days, and was 62 miles long

The Beijing-Tibet Expressway near Beijing, China was not the place to be in August of 2010! What is reported as the longest traffic jam in history lasted for 12 days, and spanned 62 miles. Web reports from the time claim that the average car speed was about 2 miles per day! Our commutes don't feel so bad anymore, now do they?

8) In Paraguay, dueling is legal as long as both participants are registered blood donors

If you're going to duel, ensure that someone benefits from the bloodshed? At least something good will come out of the duel, I guess (though donating blood somehow seems more efficient).

9) Russia did not consider beer an alcoholic beverage until 2011

Before 2011, anything with less than 10% alcohol was considered "foodstuff." Recognizing beer as alcohol has come with more regulation as well; its sale is being regulated in the same way as spirits. Beer has become increasingly popular over the years, with advertisements suggesting it is a healthier alternative to spirits.

10) The hummingbird weighs less than a US penny

Puts carrying around a few extra cents in perspective, doesn't it? It's pretty amazing that something that weighs so little can have such powerful wings, and yet, we strong humans, who are capable of lifting heavy weights, can't fly...
