Jeff used to write ads; now he directs them—which, he'll admit, isn't the most original arc, but not everything's a competition. He's built for comedy: finding the tension, sharpening the dialogue, and making it all look good, because he likes things that look good (and, well, because comedy). He's worked with some of the best agencies and brands around, and collaborators like Seth Rogen—and his friend Ian, who's also very funny.
