A saucy, Web-only ad for a clothing company has come back to haunt Sarah Green, a private-school teacher in England who’s been suspended after her students dug up the raunchy footage online. The spot, which is on YouTube, is for a company called Scruffs Hardwear, which makes clothing for construction workers. The ad shows Miss Green and other women having simulated sex with builders after being turned on by their clothing. It was filmed two years before she started her job at Stockport Grammar School in Manchester. You’ll remember that a similar thing happened to Melanie Martinez, the former kid’s-show host on the PBS-backed Sprout network.
