Ok , well I didn't know where exactly where to post this so im putting it here. Enjoy!
TREKKIE REFERENCE: In Booty Bay, just outside the inn, you’ll encounter Chief Engineer Scooty manning a teleportation device. If you have a quest that takes you through the device, you’ll find a character named Sprok and his away team.
MATRIX REFERENCE: On your way to the Ironforge Auction House, ask one of the guards the location of the alchemy trainer. One of his answers will be, “why, oh why didn’t I take the blue potion?”
FIGHT CLUB: Further into the Undercity, in the War Quarter, there’s an honest to God Fight Club where you’ll find two NPC fighters named Edward and Tyler.
GHOSTBUSTERS REFERENCE: Another movie reference can be found in the Mage Quarters of Stormwind. There, you’ll find three mages-in-training talking shop. Hang around long enough and one of them will say “wouldn’t that be bad, like crossing the streams bad?”
STAR WARS: The Shimmering Flats. Peek around a bit and you’ll find a goblin race team with a very familiar looking vehicle—Blizzard’s version of Sebulba’s podracer from Episode I. Do a little more exploring and you’ll also find a wrecked podracer which smacked into a canyon walls.
CONAN: In the Badlands around the middle of the map is a semi-hidden crypt. Enter the crypt and you’ll see a decomposed guy sitting on a throne with a sword to his side. It’s a scene from the first Conan movie.
BRUCE CAMPBELL TRIBUTE: In Dun Mo-rogh, just south of Kharanos, there’s a small camp where a group of dwarves are taking target practice. Hang around long enough and you’ll hear one of the dwarves scream out: “This is my boomstick!”
BOOK REFRERENCES: In the upper levels of Booty Bay, there’s a clothing shop named “A Tailor to Cities,” an homage to Charles Dicken’s A Tales of Two Cities. And in the Undead capital, the Undercity, you’ll find Algernon at the alchemy trainer’s holding a flower. This is a nod to Daniel Keyes’ novel Flowers for Algernon.
MEMORIAL: Blizzard designers also left a tribute to fallen comrade. In the Barrens, atop a hill just southwest of Crossroads sits a small shrine. Here, you’ll find a memorial dedicated to an Orc with the initials “M-K.” In the real world, M K was Michel Koiter, a Blizzard illustrator who passed away during production of World of Warcraft.
To reach the memorial, follow a ridge to the southeast and half-way up the hill you’ll find the base of a mound. Go up the short trail to reach the shrine. As a little bonus, if you visit the memorial in spirit form you’ll find a spirit healer named Koiter.
GAME REFERENCES: While fighting your way through the Deadmines to get VanCleef’s head you’ll encounter a Goblin Shredder. Take it down and look at the dashboard and you’ll see a familiar face: Kerrigan, The Zerg Queen from Starcraft: Brood War. She appears to be the ruler of the goblins as well. Other goblin shredders can be found in Strangle-thorn Vale and Gadget-zan.
In northern Un’goro Crater, there’s a place I’ve started calling “Camp Nintendo.” Two residents of the camp are the feuding brothers, Larion and Muigi. If those names sound a bit familiar, they should, they’re anagrams of Mario and Luigi; and the battling brothers are even decked out in red and green overalls.
Deep in the Uldaman instance, you’ll find a friendly refuge manned by three dwarves: Baelog, Olaf and Erik “The Swift.” Dedicated gamers should recognize these dudes from The Lost Vikings—the first game Blizzard created for the Super Nintendo back in ‘92.
