If there was ever an example of a marketing campaign trying to turn lemons into lemonade, this is it. Throughout his run with "The Daily Show," Jon Stewart has taken several shots at Arby's, as well as many other fast-food restaurants. Tonight is Stewart's last night behind "The Daily Show" desk, and Arby's is saying goodbye to him with class, humor and a genius marketing plan.

Set to the song, "Thank You for Being a Friend," Arby's ran the above commercial during last night's "The Daily Show." It shows clip after clip of Stewart disparaging Arby's and its food. At the end, the words "Not sure why, but we'll miss you" come on screen. That's it. It's the entire commercial — and it's an incredibly clever piece of marketing.

When I was a kid, several times a year we would travel to my aunt's house, and we would stop at a rest stop on the Pennsylvania Turnpike on the way. I would always get an Arby's roast beef and cheddar sandwich. I haven't had one in decades. After watching that commercial, I want one. I'm not going to go out and buy one (I'm not even sure if there's an Arby's anywhere near me), but despite all the negative comments from Stewart, I have a bit of a craving.

Arby's officials might not be sure why they're going to miss Jon Stewart, but I know why I am. He has a gift for entertaining and educating at the same time. He helped my kids and millions of others understand "The Monsanto Protection Act." He educated time and time again on important issues like food and climate change, while making us laugh while he did so. He will definitely be missed.
