Kevin Costner talked like a girl in "Dances with Wolves"
One of the most important parts about making a movie based in history or in another culture is getting the period or the culture right. When Dances With Wolves was about to shoot, the producers hired someone to teach the actors how to speak the Lakota language. However what they didn't realize is that the Lakota language had 'male' and a 'female' language.
The teacher they hired was a woman, who apparently didn't know the distinction. A Native American activist recalls being in the movie theater and laughing at Kevin Costner and some of the indians because they were speaking in the feminine mode of the language!
In ancient Rome, when people reached an agreement, they kissed to legally seal the contract. This practice extended to marriages as well (which were a form of contracts) and it has remained until today.
Their skeleton is made of cartilage, the same substance that your nose is made of. It's more flexible and lighter than bones are. This makes it more durable, and light, which saves them energy. This is particularly useful because sharks have to constantly swim in order to not drown. Sharks also lack a rib cage, which means that they can be crushed by their own weight on land!
Disney has really strict dress codes for their employees. This is because they don't want to ruin the illusion of the characters being real. One of the particular quirks of this dress code is that employees were not allowed to use their own underwear while in character! This is because normal underwear tends to bunch up and bulk under the costume.
Have you ever noticed that Subway is owned by Doctor's Associates? The reason for this is because the chain was started by a 17-year old kid called Fred DeLuca, who was trying to find a way to pay through his med school education. He paired up with another doctor who lent him $1000 to start his first sandwich shop in 1965.
