The polar vortex has brought more than freezing temperatures and slushy sidewalks to New York City -- now there are zombies!
Since AMC's "The Walking Dead" makes its mid-season return this Sunday (Feb. 9), the network hid zombies under subway grates for some good scary fun. It was just like any other Friday morning commute on the icy streets of New York City until, suddenly, zombie hands popped up reaching after passersby.
Watch the screaming pedestrians above and be sure to keep an eye out for icy puddles and bloody zombies wherever you go.
"The Walking Dead" returns to AMC on Sunday, Feb. 9 at 9:00 p.m. EST.
