Just in time for Father's Day, San Francisco 49ers coach Jim Harbaugh's wife Sarah has filmed a pants-related PSA warning people about the dangers of 'dad pants.' The ad pokes fun her husband's sideline style and admitted habit of wearing $8 Walmart pants, which she publicly disavowed any responsibility for during a January interview. The couple both prove to be extremely good sports in what is certain to be the most discussed Dockers ad since the one in this epic Seinfeld conversation.
