No-bark Noonan

 is a wastelander living in the Mojave Wasteland in 2281.

Background
He is mentally unstable, and has shotgun traps in his house, as well as test dummy pals.

They Went That-a-Way
You can ask him if he has seen a man in a checkered uniform (Benny); He will say he saw him running away from wanamingos.

One for My Baby
Despite his obvious madness and his seemingly random, humourous ramblings about 'chupacabras', No-Bark actually gives the player useful information about the night of the crime in the quest One for My Baby, saying that he witnessed shady goings-on at the Dino Dee-lite Front Desk.

Other interactions
You can also play caravan with him.

Appearances
appears in Fallout: New Vegas.

Behind the Scenes
He is a reference to Robert Neville in I Am Legend. He has test dummy friends like Robert, and he also tries to imitate voices, which Robert does when he is watching Shrek.
