In an effort to prove that the Arby's Roastburger isn't as greasy as other fast food burgers, Arby's created the website burgergreaseart.com and a video of an artist painting the Mona Lisa with some other fast food chain's burgers' grease. I remain dubious of Arby's claims of a grease-free roast beef. Does that even sound natural or appealing? I suppose we can argue over the epicurean value of an Arby's sandwich for years, but the video pretty much rules anyway.
