Hi, I was wondering what easter eggs there is in the game as it's a really big game there is obviously more to it that stated. Please leave various posts on the easter eggs if possible. Thanks.

If you have the Lonesome Road DLC and the Wild Wasteland trait, there are a few good ones but these ones are my favorites since I understood them right away without asking or Google-ing it first.
