5. Conan and Andy: Halo 4
Halo 4 has always been like Marmite - fan boys love it for some reason, while others see it as just another bog standard first person shooter. Not content with leaving the game as a Trilogy though- they decided that Master Chief should have one more outing. A chance for the fans to play as their favorite SPARTAN again, and a chance for the developers to make even more money. This Easter egg came about when Conan O'Brien and Andy Richter visited 343 Studios and joked about recording dialogue for the Halo 4. Fans of the duo prayed it was more than a joke, while others prayed that it just stayed as a joke. It wasn't a joke however- though their inclusion did raise a few smiles, even if the dialogue sounded familiar. To find the comedy duo- search for the two UNSC grunts near the hanger at the start of mission 6. Love them or loathe them, it was still pretty funny. http://www.youtube.com/watch?v=94vwC1sffg0
