Your mom probably doesn’t watch The Walking Dead, but when you give her the Walking Dead Complete Second Season Box Set ($40), she’ll surely be hooked. From the moment she sees the zombie head with a screwdriver plunged into its eye socket, her exuberant curiosity will take over the room. “Oooooh, I love it! This is gorgeous! I can put this on top of the china cabinet!” she’ll undoubtedly exclaim. And then you’d better make other plans for the 4th of July, because the traditional family BBQ will be scrapped as mom burrows deep in the family room to immerse herself in the zombie apocalypse. You have a cool mom.
