Oscar Mayer is selling its first-ever "Cold Dog" which is a POPSICLE. It tastes like a hot dog . . . and they say it has "both refreshing and smokey, umami notes." And it's topped with a "mustard swirl." For better or worse, it's not a nationwide release . . . yet. The "Cold Dog" is available at select Popbar locations, while supplies last. They cost $2 a pop. If you don't know, Popbar is a chain of gelato shops.
