Tom Brady is now on Twitter, and being that he sent his first tweet on April 1, it's only fitting that it was an April Fools' Day joke. "I'm retiring. In my spare time, I'll be tweeting #LFG," the New England Patriots quarterback tweeted. The Patriots' official Twitter account replied with a GIF of an unamused Michael Scott from The Office, and CBS Sports notes that some fans were shocked and dismayed at the apparent news, leading to Brady's second-ever tweet: "Was this a bad joke?" Boston.com confirms that the six-time Super Bowl champ, 41, has no plans to retire. (More Tom Brady stories.)
