In the Slaver Barracks of Paradise Falls, there is a Vault 77 Jumpsuit, with a Holotape right next to it. The Holotape is from a slaver who wants someone else to get rid of the jumpsuit that "a stranger with no name" left behind. The man recording the holotape is obviously scared and says the jumpsuit "freaks the boys out" so they must fear the stranger. The Vault 77 jumpsuit is the only one in the game and gives you a +5 to both unarmed and melee weapons.

All of these are referencing the Penny Arcade web comic "One Man, and a Crate of Puppets," which starred an unnamed Vault Dweller who was the only resident of Vault 77 and ended up hunting and killing Slavers with his bare hands and a Vault Boy puppet.
