Just looking at the event names and here are a couple:
One of the random TV show names for MPWF is "Guerras del Anillo", which is a rough translation of War of the Ring, one of the key events in the Lord of the Rings movies and books.
APW has an event titled "OzFest".......like the rock festivals, which is actually spelled "OzzFest".
CGC has an event titled "Chamber of Horrors". There is a 1966 horror film of the same name.
CZCW has an event titled "Reach for the Sky". This could be one of many references: It is the title for a song by Social Distortion, a song by Firehouse, an album by The Allman Brothers Band, an album by Ratt or a movie of the same name that starred Kevin Malone. I am guessing the Social Distortion song, but that's just me.
MAW has an event titled "Where It All Begins Again". That was the slogan for WWE's Wrestlemania XX.
The SWF has many references in the events, some intentional, some coincidence I bet.
They have an event titled "Welcome to the Jungle" like the Guns N' Roses song.
They have an event titled "Master of Puppets" like the Metallica song (also covered by Dream Theater)
They have an event titled "Time of Troubles". The Time of Troubles was a key event in the Dungeons and Dragons Forgotten Realms module, when all magic went awry and the avatars of the Gods walked the land of Faerun like mortals.
They have an event titled "When Hell Freezes Over". That's the title of an album released by The Eagles in 1994. Frost also released an album of the same name in 1997.
They have an event titled "The World is Watching". The slogan "What the World is Watching" was once used by the WWF/WWE.
They have an event titled "Break Like the Wind". That was the title for an album released in 1992 by the semi-fictional band Spinal Tap.
Over in TCW:
They have an event titled "Hotter than Hell". That is the title of the second album by mega popular rock band KISS.
It is fitting that they also have an event titled "Psycho Circus", the same title as the 1998 album by KISS.
They also have an event titled "Excessive Force". That was the name of a side musical project by members of KMFDM and My Life with the Thrill Kill Kult groups. This one is pretty obscure, but it might be a reference.
They have an event titled "A Little South of Sanity" which was the title for an Aerosmith album.
They have an event called "Where the Angels Fear to Thread". I am not sure, but a friend of mine says it is a reference to the anime Neon Genesis Evangelion. I am not sure, for I have never seen the series myself.
They have an event titled "Just Another Day?" John Secada and Queen Latifa have songs of the same name. Also it was the title for a 1986 episode of Pee-Wee's Playhouse.
They have an event titled "The War to Settle the Score". I am not 100% sure, but I think that was the name of a WWF event in 1985 headlined by Hogan vs Piper. That match appears in one DVD which title eludes me, but is the one that features several 80's legends like Hogan, Piper, Flair, Slaughter and some others.
Also, WLW has an event called "Power & Glory". I pray to God it is not a reference to the very bad 1991 WWF tag team composed of Hercules Hernandez and Paul Roma....
Also, BHOTWG's TV Show is called "Lords of the Ring", another reference at the books and films, Lord of the Rings.
