Usually when celebrities star in internet videos they are either having sex, hitting moving vehicles with umbrellas or diving drunk into Christmas trees, but rarely do you see them interact with fans and be nice about it, but check out John Krasinski, Jim from 'The Office', stop and be what appears to be genuinely nice and grateful to his fans.

Way to go John, way to show you care about the people that support what you do, even if half those signed pictures ended up on eBay, the effort is noticed, keep it up.
