A T-shirt that reads "I'd rather shower at Penn State than cheer for the Wolverines" went viral Wednesday, causing a bit of an uproar.

We recently became aware that this T-shirt design is circulating on social media," Gayle Saunders, OSU assistant vice president of media relations, wrote in an e-mail. "This is not a University sanctioned T-shirt, and we have no knowledge of where it originated. It is unacceptable and appalling that someone would make light of a tragedy in this manner."

The "shower at Penn State" line refers to a 2001 incident involving Sandusky, the former Penn State assistant football coach. Then-graduate assistant coach Mike McQueary testified he saw Sandusky rape a boy in the showers of the PSU football building.

Penn State declined to comment on the T-shirt.
