France has a lame version of Mythbusters called "On n'est pas que des cobayes" (We're not just guinea pigs), broadcast on educational public TV network France 5.
You can watch it (in French) for a few more days here: http://www.pluzz.fr/on-n-est-pas-que-des-cobayes-2012-02-17-20h35.html
Hélène Clauderer, an "expert" from a company called the Centre Clauderer, is brought in with her microscope to tell us which of the three hosts has the strongest hair. She also explains that you can tell the personality of people by the structure of their hair.
She's asked: "Is is true that with a person's hair you can tell their characteristics?"
She answers: "Yes, but first I have to show how the microscope works."
She examines the hair of the first host and says: "We see you have an excellent diet. We can also see that you're very emotional. You speak your mind, and quickly."
The host asks: "How can you see that?"
Reply: "In the structure of the hair. That's it."
About the next host: "Vincent has a hair that would be great for pulling a car. You are very determined. When you decide to do something, you really do it."
The last host is healthy but "is very stressed".
