It’s been an up-and-down week for Steelers running backs on Twitter.

Monday, DeAngelo Williams called out Peyton Manning’s less-than-stellar final season, and even caught some heat from his head coach Mike Tomlin for something he was actually mostly right about. Tuesday, Le'Veon Bell took his turn, saying in a video he had never heard of International Women’s Day.

To Bell’s credit, he said he would still celebrate the holiday, even though in his previous 24 years of life he had never heard of it.

The earliest Women’s Day celebration was observed in February 1909. In the U.S., International Women’s Day has been observed by most since 1977, though many women recognized it for decades before. And the United Nations has given each International Women’s Day a special theme since 1996.
