I wonder if emergency rooms keep the stats on zipper injuries.
Must be a lot of people going commando.
"An estimated 17,616 people went to the ER from 2002 to 2010 with genital injuries caused by zippers. The overwhelming majority of those were penis-related injuries, though five reported injuries were to labia or vaginas."
"Of all the ways a penis can be seriously hurt, zippers were the single leading cause of penile injuries requiring an ER visit, followed by bicycle injuries."
This has been a public service announcement.
