Marvel delivered some big revelations in this week’s issue of Thor, but writer Donny Cates and artist Aaron Kuder also slipped in a delightful easter egg for those who decided to pick up a phone. It all stems from one of the big plot points in the issue regarding Thor’s hammer Mjolnir, which Thor sets down for someone else to find. A man named Adam Aziz is the one who stumbles upon it, and later in the issue, we see Iron Man arrive on the scene. That’s when Tony asks how he called him on his personal number, and it is revealed that Tony’s number is on Mjolnir, and the whole thing gets even better when you realize that it’s an actual number that you can call to get a voicemail from Tony himself.
