A reddit user has found a very clever easter egg that references The Wyatt Family, who are a group in WWE. The reddit post says
So I’m playing the new fallout 4 DLC, Far Harbor, and I came across a place called Rock Point Camp. There are a series of Holotapes around the camp, in which the camp leader, Bray, is telling 3 campers what the chores in camp are and so on. The 3 campers names are Luke, Rowan and Braun.
There must be one or two developers of Fallout 4 who are WWE fans as those 4 names are the names of each member in The Wyatt Family. Here are some images also confirming the easter egg.
