Arby's is out-doing its 13-hour, Guinness World Record-breaking ad showing brisket being smoked, proof that Arby's really does smoke the meat in its Smokehouse Brisket LTO sandwich. The company is going to create an even longer commercial with even more smoked meat, this time in collectible DVD form: Arby's will hand out 500 six-DVD box sets featuring its original brisket commercial — plus an extra eight hours.
