This is the moment a teenager with Down's syndrome sunk an incredible trick shot during halftime of his high school basketball game. James Meiergerd, 18, from Omaha, Nebraska was filmed throwing a basketball backwards, from halfway down the court. The video of the highly-skilled trick shot has gone viral and even attracted the attention of the Harlem Globetrotters, who have invited him to be a guest when they play a game in Omaha in April.
