Seth MacFarlane‘s American Dad! hits two major milestones this year, with the long-running animated series celebrating its 15th anniversary and set to air its 300th episode this September. So when a team from the TBS series made their way to this year’s Comic-Con@Home, they were riding high and looking to offer viewers a different take on the con panel. Series supervising director Brent Woods offered us- as well as the series’ cast and executive producers – a “how-to” lesson on how to draw Roger. Joining Woods for the illustrating event were Rachael MacFarlane (Hayley), Wendy Schaal (Francine), Scott Grimes (Steve), Dee Bradley Baker (Klaus), and executive producers Nic Wegener and Joe Chandler (panel video here).
