Yes man

Yes Man was originally a generic Securitron robot programmed to work for Mr. House like all the other Securitrons found on the Strip. He was recovered by Benny and several of the Chairmen after being damaged by a pulse grenade. Following this incident, Followers of the Apocalypse member Emily Ortal examined the Securitron in order to learn Mr. House's secrets in exchange for reprogramming him for Benny's personal use.[1]

The reprogramming was extensive, and resulted in Yes Man being designed to do exactly as he is told; thus, Yes Man is not just the program's name, it's also his job description. Yes Man is completely incapable of declining any order or withholding any information he is asked for, no matter who he is interacting with

Overall, Yes Man is cheerful and positive, providing an ironic juxtaposition to the wasteland around him, especially because he has no expression other than smiling. Because he is programmed to be unable to say no to anyone, so the most angry he can get is being passive aggressive he also won't hesitate to speak his mind out
