TV Article Last Week Tonight sex ed video includes Laverne Cox, Nick Offerman, Kristen Schaal By Jonathon Dornbush Published on August 10, 2015 03:12PM EDT Photo: HBO John Oliver is worried about how thorough your sex education was in high school, so he asked a few Last Week Tonight friends to help teach audiences. Oliver enlisted Laverne Cox, Kumail Nanjiani, Kristen Schaal, married couple Nick Offerman and Megan Mullally and many more to deliver a sex ed video that makes sure not to be ambiguous or misleading about how sex actually works in today’s society. The host spent the main segment of this week’s episode taking a look at America’s sex ed policies — or lack thereof, as he discovers — and just how sex ed videos, speakers, and teachers have created a lack of understanding when it comes to sex, consent, and more. Whether Oliver’s sex ed video is screened in classrooms anytime soon, he hopes anyone seeing it will actually learn a thing or two, for everyone’s sake. Though you may end up learning even more than you would have wanted about the celebrities’ sex lives as a result. Watch the video above to see Cox, Offerman, Aisha Tyler, and even Jonathan Banks — who hopes to make up for the mistakes from his past life as a sex ed video actor — talk about sex, baby. •John Oliver slams mandatory minimums, demands more reform on Last Week Tonight •Last Week Tonight segment on food waste reveals 40 percent of food produced in U.S. never gets eaten •Caitlyn Jenner gives Last Week Tonight segment on transgender rights her stamp of approval HBO
