Gwyneth Paltrow’s return to Fox’s hit show “Glee” is drawing near and it looks like it will be a blockbuster episode. Her sassy substitute teacher character drops in on the Glee kids to teach them a thing or two about safe sex… in song of course.

Sex ed teacher Holly Holliday (Paltrow) begins her lesson on safe sex with a lecture, but before long she breaks into song. But not just any song.

She kicks off Joan Jett’s racy “Do You Wanna Touch Me” with a brassy “Hit it!”

“I happen to be an excellent educator,” Schuster responds.
