On her press rounds promoting Night School with Kevin Hart, Tiffany Haddish stopped by The Late Late Show to give out some pristine sex advice to James Corden’s audience. In the clip below, when Corden asks Haddish what class she would choose to teach, she quickly replies “sex education.” Her first lesson? Hygiene. “Good hygiene equals good sex,” she says. “I would tell the women, the young ladies in my class, look you gonna have to take a bath at least once a week. You gotta drown. You gots to drown it. And put like a half a box of baking soda in there, get the pH balance right.”
