We're funning it up

Two men are in a moving car, with the man in the passenger seat looking at the camera and then making a series of exaggerated facial expressions while the driver looks forward. The man in the passenger seat, wearing a black t-shirt, looks at the camera, then brings his arm up to cover the lens, then reappears with sunglasses on, making a loud, open-mouthed expression, and finally returns to a more neutral expression while the driver, in a patterned black t-shirt, keeps his gaze forward.
