Ne Ne Ne Ne... is a one-star (★) challenge added in the Fallout: New Vegas add-on Gun Runners' Arsenal.

Challenge requirements
The Courier must cripple five right arms with any shotgun (except the sturdy caravan shotgun).

Behind the scenes
This is a reference to the film RoboCop, in which Alex Murphy has his right hand shot off by Clarence Boddicker, who utters a beeping noise sounding like 'ne ne ne ne' beforehand.
