Homeless man receives thousands from strangers

A 24-year-old guy named Philip Vu quit his bank job a while back to live out of his car and travel. And along the way, he made friends with a homeless guy named Mike. Philip thought he was so interesting, he started posting videos of their conversations online, and they went viral. Then people reached out to ask how they could help Mike . . . and ended up donating $17,000. Here's how he reacted when Philip gave him the first $1,000 in an envelope.
