Season two's "Thanks For the Memories" will have you feeling super nostalgic as it centers on the ABC hit's OG interns. George (RIP!) is forced to go turkey hunting, Izzie (somewhere far, far away!) tries to throw the ultimate holiday dinner and Meredith, Cristina (miss you every day!) and Alex (How dare you, sir?) hide out at the hospital. And if that's not enough nostalgia, there's some deliciously torturous Mer-Der drama and that Fall Out Boy song thrown in for good measure. Oh, the 2005 memories. (Where to Watch: Netflix)
