Like Forrest Gump's mama always said, "Life is like a box of chocolates. You never know what you're gonna get."

For one little girl, that was never more true.

Check out this video of a little girl donating money to a street musician. He begins to play for her after putting a coin in his hat, only to ultimately give her -- and the hundreds around her -- the surprise and experience of a lifetime.

Watch until the end. You won't regret it.
