Crazy, Crazy, Crazy

Crazy, Crazy, Crazy is a side quest

Detailed walkthrough
Upon approaching Neil's shack or Black Mountain from Hidden Valley, a Super Mutant named Neil will run towards the Courier and start dialogue. He will inform them that the area is dangerous as a super mutant named Tabitha has taken over Black Mountain. One of her rules is that no humans are welcome in the area, and any that approach are to be killed on sight. This will automatically start the quest, which requires the Courier to enter Tabitha's stronghold and put an end to her chaos.

Neil will say that the area is patrolled by super mutants during the day, while at night, cloaked Nightkin patrol the roads. With a Speech check of 50, Neil can be convinced to assist in killing Tabitha. From Neil's shack, the Courier will have to make their way up the road towards Black Mountain. There is a long way where one will have to fight against three patrols and checkpoints of super mutants or nightkin. Upon reaching the toppled satellite dish by an irradiated crater, there is a ham radio under it which can be used to talk to Tabitha. There are 3 dialogue options, or 4 with low Intelligence:
 * Telling Tabitha the "dumb-dumbs" are taking over, or if Neil was convinced to help, that the super mutants are following him now, which requires a 75 Speech check, will cause her to sentence them (non-nightkin super mutants) to death. Fighting will then break out between the super mutants and nightkin. The super mutants usually win the opening fight and are then attacked by more nightkin. If the check is failed, she will recognize the Courier and send super mutants towards the dish.
 * Saying one is a big fan of the super mutants will result in Tabitha sarcastically thanking them and sending the remaining super mutants in the area towards the dish.
 * Say nothing, which will irritate Tabitha and cause her to ignore the radio afterward.
 * With low intelligence, a dialogue choice labeled "[Dumb] What?" will appear. After choosing this option, Tabitha will dismiss the player character as a "dumb-dumb," and cut off the conversation.

There are also two shortcuts to the summit to avoid most of the super mutants:
 * On the way up will be a body of an NCR trooper. There is a bear trap at the legs of the corpse and more all the way up to that hill. Be careful to avoid bear traps and falling rocks if one chooses to take this path. There will be a warning sign about rock falls halfway up the path. A little beyond that point a trap is triggered and a giant boulder rolls down the path, which can be avoided by backing down the path until it flares out to the right or left and hugging the rocks to the side. After walking up this shortcut, the player character will only have to deal with the super mutants at the toppled satellite dish to reach the summit.
 * Traveling north from scorpion gulch, follow the canyon to an irradiated crater with centaurs and a dead paladin patrol from the Brotherhood of Steel. Kill or sneak past them and climb the ridge to the east. This leads to a hard locked gate into the Black Mountain compound, bypassing Neil and the super mutant patrols.

Once the summit is reached, the super mutants at the compound can either be killed or drawn away by asking Neil for help. This requires moving stealthily past the guards. When Neil returns from giving false information about "an intruder in the entrance of the Black Mountain," he will start walking back towards his previous location with a number of cloaked nightkin directly behind him to check out the entrance of the area. Note that if the player character chose to bypass Neil and kill the nightkin at the summit by themselves, talking to him later will have no effect. At this point, one can choose to complete the quest in one of three ways.
 * Enter the storage building at the top of the mountain, where the player character will find a disabled robot named Rhonda. If one decides to repair Rhonda, which requires a Science Skill of 60, they will receive the good ending of this quest: as one leaves from the storage shed, Tabitha will appear, happy to see her robot repaired and fully functional again. She will give them a key to open various containers in the building, and the quest will finish with good Karma. After doing this, Tabitha and Rhonda can be killed and looted with no Karma penalty. Raul can also be freed without Tabitha becoming hostile.
 * Enter the broadcast building and simply kill Tabitha. This carries no Karma penalty. With a Science Skill of 25, Tabitha's personal computer can be hacked (it does not have a special name, being simply labeled terminal). The last entry in this terminal says that Tabitha hides a second key to her personal room (where she can be found) below the stairs leading to her room. The key has the appearance of a small rock and can be tricky to pick up.
 * Enter the prison building and release Raul. The building has 2 terminals, one opened and one very hard locked, and a door that requires a key. The first terminal contains Raul's diary; reading Entry 6 will reveal the password (123456789) for the other terminal. The second terminal will now open the door. After talking to Raul inside and setting him free, Tabitha along with 2 nightkin will ambush the Courier as soon as they leave the building, screaming "No! I won't let you have my Raul!". Killing her will complete the quest.
