Is it super-dangerous to film yourself impersonating Sofia Vergara while behind the wheel of your car? Probably! But that doesn’t stop comedian Lauren O’Brien, who, since she lives in Los Angeles, often finds herself stopped in traffic. Most people pass the endless hours they’re stuck between a manure truck and a guy with a “my other car is a Millennium Falcon” bumper sticker by screaming at the radio. Not O’Brien, who records Vines of herself pretending to be Ellen, Lena Dunham, and Mindy Kaling. They’re pretty great.
