"This is only the beginning. I am truly grateful and most appreciative."Unsurprising for an apparent Boston sports fan, based on posts from his social media accounts, Missler’s tweet included a gif, or an animated image, of Boston Celtics’ power forward Kevin Garnett basking in the glory of winning the 2008 NBA championship. The gif was captioned, in all capital letters, "ANYTHING IS POSSIBLE!"Missler opted for the lump sum Mega Millions payout of $281.9 million.
