If you’ve ever wondered why victorious Olympians so often bite their medals, it’s because photographers ask them to, according to Bustle.com.
Twelve-time Olympic medalist Natalie Coughlin said about the eager photographers, “They wear you down and they make you bite it. That's why you see all those pictures of people biting the medal; it's not like we just come up [on the stage] and we bite it. They make you do it."
