Fortune: If you’ve ever made up an excuse to avoid a boring meeting or bad date, entertainer Chelsea Handler approves. In fact, she’s even created a mobile app to help make your excuse more believable. Handler’s “Gotta Go” app lets you set up a fake phone call or text message that can provide you with an excuse that you, well, gotta go. The app’s creation is documented in the second episode of Handler’s new documentary, “Chelsea Does,” on Netflix.
