Wild Wasteland

 is a trait which only appears in Fallout: New Vegas.

Wild Wasteland unleashes the most bizarre and silly elements of post-apocalyptic America. Not for the faint of heart or the serious of temperament.

In an interview with Chris Avellone, he notes that the Wild Wasteland trait may add more references to older content in Fallout and Fallout 2, in regards to special encounters. Players without Wild Wasteland will find less silly analogues in places where Wild Wasteland modifies things. According to J.E. Sawyer, the trait was added as a compromise because different members of the team often suggested 'wacky' content that others thought would be out of place. One of the events that can happen is a reference to the movie Indiana Jones: Kingdom of the Crystal Skull when a flying refrigerator falls from the sky and inside is a skeleton with a whip and a fedora.(this resembles the scene from Indiana Jones when Dr. Jones hides in a refrigerator to escape a nuclear blast.)
