We wish every Monday brought us a bromance as majorly meta as this. It all started a year ago, when Ryan Gosling was snapped wearing a t-shirt of Macaulay Culkin from his Home Alone days (hunky refresher below).

Now this past Sunday, Culkin posted a pic of himself on his band Pizza Underground’s Twitter page sporting a one-of-a-kind throwback Gosling tee. (Oh, boys!) But no, it doesn’t feature an adorable screenshot showing a feathered-haired Gosling from The Mickey Mouse Club, or even a still from the former child star’s epic ’90s dance routine — it’s much more clever than that (after all, we ARE dealing with Kevin McCallister here). Macaulay Culkin is wearing a t-shirt of Ryan Gosling wearing a t-shirt of Macaulay Culkin:

The mind warp is made even more insane by the fact that Culkin is holding up a Pizza Underground coffee mug WITH HIS FACE PRINTED ON IT, shoulder length scraggly hair, sunglasses and all (WHAT!). We’re hoping Gosling’s got an equally awesome follow-up: a t-shirt of Culkin’s Twitter pic, perhaps? We’ll run with the joke as long as this duo does.
