Bones hadn’t seen him yet and before they went on camera, McGraw told him he had a big hair hanging out of his nose and reached over and pulled it out. He loved that he felt so comfortable with him to be able to do that, and Bones said he would've done the same for McGraw if needed. He did see McGraw wipe his hand before the camera went live and they started talking.
You can see the moment happen in the video above and on Bones Instagram!
