Ever since the first Iron Man movie when Nick Fury appeared in the post-credits scene, or when Samuel Sterns' head began to mutate in The Incredible Hulk, or when the map of key Marvel locations was seen in the background in Iron Man 2, eagle-eyed and keen-eared viewers have been looking and listening out for fun little inclusions in the Marvel Cinematic Universe.
