"Do you always work out in front of a cardboard cut-out of yourself?"
James Corden has been on a roll recently with his side-segments where he does little activities with celebrities on his show The Late Show With James Corden (the Migos edition of Carpool Karaoke is priceless). They're always fun to watch, perhaps because Corden has a unique ability to make the videos feel intimate and draw these people out of their skin but also to heighten the more caricatured aspects of their public persona.
Most recently, Corden did this with Mark Whalberg. Not only this, but he did it at 4 am. The segment shows Corden filming himself as he wakes up in his house at 2:30 in the morning, using his iPhone camera since the camera crews haven't arrived yet. He showers and yawns his way into the car and through deserted streets to Mark Whalberg's house where Whalberg admits that he actually stayed in bed till 3 that morning (!). Next, the two work out together. Whalberg takes Corden through all the steps of his daily routine and Corden honestly does a good job keeping up with a guy who wakes up at 2:30 every morning and has two meals before 6. Corden finishes the routine by giving Marky-Mark some "merch:" t-shirts with muscular characterizations of Corden and Whalberg with "4 AM Club" written on them.
