In his most recent video, YouTube prankster Jerome Jarre asks the question, "What happens when you give back to those who give?"
On a 20-degree December day in New York City, Jarre and a violinist friend camped out on the street, their shoulders hunched over, their expressions morose. Jarre held out a small jar, as if asking for change.
The kind New Yorkers who then donated to the pair didn't expect what happened next.
In the midst of a very chilly holiday season, this video is a heart-warmer.
