John Mayer was on Andy Cohen's radio show and had a great story about how he ended up with Shawn Mendes' underwear. The story goes, the two were working in the studio and Shawn said he was out of underwear. He asked John if he thought Postmates would get him underwear. John said, "Don't Postmates underwear, my assistant will get you some underwear." Just listen to the story!!! It's good!
