Captain America: Civil War - 15 Obscure Easter Eggs You Probably Missed

2. The Spider Signal

In the post-credits stinger, we get to see more of Spider-Man after he returns home from duty with Iron Man, making a great little gag about fighting a guy from Brooklyn with a "huge" friend.

As he's talking to Aunt May through his door, Parker fiddles with the new web-shooters Tony Stark gave him, unwittingly beaming a Spider-Man logo on the ceiling. Obviously what he sees is some sort of AI menu, as it has icons around the central logo, but the whole thing is a reference to an old ability that was built into the Spidey suit.

The beam of light is clearly a reference to the old school Spider Signal that Spider-Man used to ridiculously shine onto the floor or walls before he entered a room, giving his enemies time to prepare for some reason.
