Private Davey Crenshaw is an NCR foot soldier guarding the grounds close to the rear walls of Camp McCarran. He was placed there by Colonel Hsu after he got sick of the pranks Crenshaw would pull on him and the other soldiers. When first confronted, Private Crenshaw will tell the player to stop disturbing his routes, later he reveals that he really is just thinking of new pranks to pull.
I Put a Spell on You: If you choose the Legion's side, Crenshaw is to be killed in order to frame him for destroying the NCR Monorail. Because he is well known as a prankster, when you talk to Colonel Hsu, he will believe that Crenshaw planted the bomb on the monorail.
"Aw, usual stuff. Brought a brahmin upstairs in the terminal once. They can go upstairs but not down. Two heads and both of 'em dumb as stumps. That got me some detention time, but it was worth it 'cause they couldn't get the brahmin back down, so it visited me a few times in my cell. Dropped some firecrackers in the toilets too. That was the real bad one for me. Turns out there's no way to replace the toilets now. Toilet company blew up in the War. I think they'd just have shot me if they weren't shorthanded."
