Fallout: Beginning Vs. End (i only have Fallout 3 and New Vegas, i don't have Fallout 4 yet, but I've heard talk that you get pretty decent armor and weapons right at the beginning... Anyone wish to clarify this?)
I looked this video up on YouTube and it's called "Sitting and Smiling #5" and at around 2:36:30 a robber does come through the door and says "hello?" then leaves. The guy sits there smiling for an hour and a half more.
