Why is it that we get so much joy out of other people's misfortune, especially when they fall, get scared or walk into something. The folks at America's Funniest Home Videos have created an empire out of the dumb, cute and weird things we do. When someone walks into something or trips for no apparent reason, you laugh...every time...why? Because it's funny! This video is a compilation of people walking into things and it's pretty funny even though some of them looked rather painful. I myself have walked into a closed screen door, much to the delight of the people in the room...we all have. Watch below and enjoy.
