I'm My Own Best Friend is an achievement/trophy for Call of Duty: Black Ops II in the zombies map Die Rise. It requires the player to revive themselves using Who's Who. This is done by downing oneself (where the player can still be revived, i.e. not falling down the building or an elevator shaft, or being crushed by the elevator), taking control of the doppelganger Who's Who creates, then going up to the real character and reviving them.
