Simpsons Video: Kaitlin Olson and Lisa Team Up to Stop Social Media Snafus

Lisa invents her first phone app when The Simpsons returns Sunday (Fox, 8/7c) — but there’s something Sunny funny about her new business partner.

Kaitlin Olson (It’s Always Sunny in Philadelphia) lends her voice to Quinn, a teacher who helps Lisa develop a program (voiced by Hello LadiesStephen Merchant) to prevent Springfield residents from posting regrettable photos and messages on social media — easily the Simpson clan’s finest contribution to the tech world since “Homer’s Web Page.”

But before it all blows up in their faces — I’m assuming, given the series’ track record with wacky inventions — please enjoy TVLine’s exclusive behind-the-scenes look at Sunday’s winter premiere.
