We're pretty sure this is a major moment in Twitter history. Shaquille O'Neal just became the first-ballot NBA Hall of Famer to retire via video posted on Twitter. That's right, America, the Diesel uploaded a video 31 minutes ago with the simple message of im retiring Video and #ShaqRetires. See the video here. Sad to see him go. Maybe we'll get another season of those smash hit Shaq vs. shows on ABC. Can't wait.
