Macaulay Culkin may have just created the most meta thing of all time. Behold: a picture of the actor wearing a T-shirt of Ryan Gosling, who's wearing a T-shirt of Culkin. He tweeted the photo to promote his band, the Pizza Underground. Yes, he's also holding a mug with pizza slices on it. Herein Culkin reminds us that though he's still young and hip. He's certainly not the 6-year-old boy who wonders whether a toothbrush is FDA approved or not. He's in a band. He uses all of the hashtags. He is epic.
