Cliff Briscoe

 is the owner of the Dino-Bite Gift Shop in Novac.

Background
He is oddly obsessed with selling the T-Rex souvenirs and the Rocket souvenirs, probably because he has an incredible amount of them (his shop inventory shows 1000 T-Rex souvenirs for sale for 1 cap each). There are also a lot of Dinky souvenirs placed in his house next to the Gift Shop.

Quests

 * One for My Baby: The player meets and questions Cliff about the disappearance of Boone's wife. Cliff will mention he didn't really like Carla. Like many other Novac residents, Cliff can be used to satisfy Boone's blood-lust. Doing so will affect your karma negatively.

Other interactions
When the player first meets him, Cliff will exclaim that the Courier has made it just in time, with only a few T-Rex souvenirs left in stock for purchase, though the truth is that he has a ridiculous amount of them. He eventually admits that "no one ever buys the T-Rexes." His shop opens at 6:15 AM.

Appearances
appears in Fallout: New Vegas.

Bugs

 * If the player trades over 30,000 caps to Cliff, his cap amount will not lower when the player attempts to sell items back. This makes it possible to play caravan indefinitely, as Cliff will never lose caps.
 * If the player attempts to win more than 50,000 caps from Cliff in a game a caravan, the game will freeze.
 * In some instances, the game will freeze every time the player tries to complete a transaction with Cliff. Resetting will not resolve this issue.
 * When attempting to purchase Cliff's Cowboy Repeaters, caps will be deducted but when completing the transaction the Repeaters will not appear in your inventory and instead will reappear in Cliff's inventory; but as a single Repeater that has been repaired with all that he had available. Strangely, upon leaving the store, all but one of the purchased Repeaters will now appear in your inventory and the repaired Repeater that had reappeared in Cliff's inventory will still be there.
 * Sometimes when looking for Cliff he's not there. The reason for this is that he's sunken under the floor. If you look at the floor you will be able to trade with him and he pops out from under the floor. Then, when you're done talking, he will sink slowly back under the floor. (Not confirmed for ALL PS3 players, as this has only happened to me once. I'm not sure if this has happened to anyone else.)
 * To get unlimited weapons, ammo, apparel, etc. just find a weapon that he has 2 of and buy the cheapest one. When you buy the cheapest one of the two, sell it back and you will notice that it is in perfect condition resulting in more caps for you. Keep doing this to until you have what you want and when he is out of caps, wait for 3 days and he will be resupplied.
 * While the step to gain radioactive fuel for the rockets is open during the quest Come Fly With Me, with a 40 Science, the player can pass infinite speech challenges while inquiring whether Cliff's rocket toys have radioactive material in them. Note this speech challenge gives no XP, and the speech challenge dialog does not appear at all unless the player has at least a 40 Science (as opposed to normal speech challenges which appear as dialog options even if the player will fail them). It then becomes an easy way to rack up 50 speech successes very quickly for the achievement. If you have gained the radioactive fuel by stealing/buying 3 of them from Cliff, or picking up the Isotope-239 from Mr. RADical's corpse, this dialog option disappears forever.
