Will thanked his friend for the warm welcome by posting his first ever video to his account reminding him that he "knows what throwback Thursday is." 

"I'm not like...I ain't been in a hole," he says letting JT know that he's current. "You know, and I heard you doing the Super Bowl so I wanted to help you out - just the things to avoid," he adds, in reference to when Justin Timberlake exposed Janet Jackson's breast at the 2004 Super Bowl. Will then points the camera to this own nipple and tells JT to "avoid that."
