|關於the random encounters appearing in Fallout，參見Fallout random encounters。|
These encounters are included purely for humor and/or easter eggs, and are random events that may or may not happen, depending on the player's Luck. They should not be considered canon. They can only be encountered on Desert squares on the world map, and will be represented by a "target" icon when encountered, as opposed to the lighting bolt icon that displays for normal encounters.
There is a UFO with two dead aliens beside it. One of them has a unique alien weapon, whereas the other has a fuzzy painting of Elvis. By looking at the UFO you discover a small label that reads: "Property of Area-51. Return if found."
Used cars for sale; pick your way into the loony salesman's house to get the Red Ryder BB gun from a locked box on the left, then check the right side of the house to find a box containing the better Red Ryder LE BB gun.
A rather strange and spontaneous herd of 6 brahmin appears in the desert. They wander aimlessly around you and shout phrases such as "Moo!" or "Moo, I say."
Giant footprint in the ground with the remains of a crushed peasant, search the remains to find a Stealth Boy.
Crashed and left alone in the middle of the desert, with a potentially huge amount of bottle caps in a crate behind it, depending on the player's Luck.
The amount of caps found is doubled if the character has the Fortune Finder perk.
You see a strange, out-of-place object in the middle of the desert. The object seems familiar for some reason. Examining the box will give the flavor text: "A police box from the UK, circa 1960." The object certainly appears to be a police call box, but suddenly it's not what it seems to be when the object disappears into thin air as you go towards it. After the police call box disappears, it leaves behind a motion sensor, thus revealing itself to be a TARDIS spaceship, in reference to the British science fiction show Doctor Who.
