Saw the preview of the new tv with Sheldon from big bang. He said if his physics career did not pan out that one of his back up plans was hobo. Now, we already know he is a train enthusiast, but can you imagine him as a train hopper. I myself have not "yet" done it. But can you imagine! Let us try to think of scenarios he mite face and how he would react. Also, how would you expect to react to a hobo Sheldon?
