Ainge's first Tweet: Ice Bucket Challenge

Boston Celtics president of basketball operations Danny Ainge made the most of his first official Tweet, posting video of a grandchildren-assisted Ice Bucket Challenge to his account @DanielRAinge:

As part of his challenges, Ainge called out Celtics owners Wyc Grousbeck and Steve Pagliuca, while also challenging former teammate Kevin McHale.

It's been a busy couple days for Celtics-related Ice Bucket Challenges. Jeff Green also posted his Ice Bucket Challenge on Wednesday.
