Gob

 is a ghoul bartender who works at Moriarty's Saloon in Megaton in the year 2277.

Background
Gob used to live in Underworld with his adoptive "mother", Carol, in Carol's Place. He set out into the Wasteland to find fortune and was caught by a group of slavers. Colin Moriarty then purchased him to be his slave. He works for Colin Moriarty to repay the debt presumably incurred when Moriarty purchased Gob from the slavers. Gob has been working to repay his debt for 15 years, since Moriarty, who mistreats him, also charges Gob for rent and food.

On a more personal note, if you're following the main quest as soon as you leave the vault, Gob seems to be one of the most friendly of the first people you meet.

Daily schedule
Gob spends most of his time serving drinks and talking with the patrons in Moriarty's Saloon. At night, he'll eventually go to sleep in the rentable room, sometimes resting for a few hours and then starting up the saloon in the early morning hours. During his working hours, he'll be cleaning glasses, communicating with people (What, you never seen a ghoul before?) and tidying up the place with a dirty broom. The first time the player enters the saloon, Gob will be relentlessly trying to fix the radio located on the table, with Nova trying to explain to him it doesn't work. However, after the player completes the Galaxy News Radio quest, the radio will function properly.

Quests

 * Following in His Footsteps: If you pass a speech check with Gob, he will tell you about Moriarty's terminal. If you ask him about the terminal afterwards he will reveal that Nova has the password.

Other interactions

 * When first meeting Gob, treating him kindly will open up generous discounts, gain the player some good karma, and reveal some more of his personal past. The discount is especially useful as Gob remains a cheap source of stimpaks for the entire game. You lose the chance to obtain this discount if you first talk to Gob after Moriarty is killed.
 * If on first meeting the player says to Gob, "Gah! What the fuck are you?" or, "Stuff it, ghoul.", he will refer to you as a dick every time you ask for a drink.

Effects of player actions

 * If you kill Moriarty, Gob will eventually take over the saloon and place his name over Moriarty's on the front sign. Nova will begin running the hotel and quit prostituting once Gob is in charge.

Notable quotes

 * "Wait? You're not gonna hit me? Yell at me? Not even berate me a little bit?"
 * "Well, now that's a surprise! I'm used to every smoothskin in this town giving me shit 'cause I look like a corpse."
 * "Moriarty'd have my head if he saw me chargin' at a discount, but for you, I'll risk it."
 * "If you ever make it to Underworld, tell Carol I said hi."
 * "Oh, hey! I'm glad you´re here. Moriarty's been especially nasty lately and I needed a friendly face."
 * "Goddamn radio won't work!"
 * "Don't hit me!"

Appearances
Gob appears only in Fallout 3.

Behind the scenes

 * There is a slight inconsistency regarding the origin of Gob's name. While yelling at Gob in random NPC to NPC conversation, Moriarty says, "Shut yer gob, Gob! Ain't that why I named you that to begin with, 'cause you talk too goddamn much?"; The term "Gob" comes from the English slang for "mouth", yet Carol knows exactly who the player means by "Gob."

Bugs

 * If the player manages to complete the Galaxy News Radio quest without ever stepping foot into Moriarty's Saloon, Gob will still complain about the radio's reception upon entry to which Nova replies, "I told you Gob, it ain't the radio... it's Galaxy News. Their signal's been shit lately."
 * In NPC-to-NPC conversation, Gob could be heard telling Moriarty "What's the matter never saw a Ghoul before?" regardless of Moriarty's status.
