Sleeping Guy

The Sleeping Guy is an NPC in Fallout 3. He isn't an NPC in the traditional sense; he is found only in the Developer's Room, which can only be reached by using console commands (coc testqaitems).

He is found sleeping on a mattress. If you wake him up and try to talk to him he'll just walk around, if you try to kill him he won't attack back and has a big stash of items.
