Stand up moment for Bernie Sanders.
Sanders briefly halted a campaign event in New Hampshire Thursday to try to help a man who collapsed on stage.
"Oh my God," Sanders said when the man fell just after the Democratic presidential candidate was taking a question in Concord about the schedule of debates. The scary thump could be heard on video that captured the moment.

Sanders waited near the man until he was helped off the stage about a minute later.
The specifics of why the man had collapsed and his condition after walking away were not immediately clear.
The man was a supporter of Sanders who worked for the state chapter of the Sierra Club, according to The Wall Street Journal.
It wasn't the first time Sanders was caught on video trying to aid someone in distress.
The Vermont senator yelled at camera crews to back up when NBC News' Andrea Mitchell was reportedly nearly crushed by other members of the media following a Democratic debate in October.
Sanders will face off against Hillary Clinton in a debate on MSNBC later Thursday ahead of the New Hampshire primary on Tuesday, Feb. 9.
