It became a running gag in Marvel movies and TV shows that Stan Lee would pop up at any moment.

Starting with a cameo on The Incredible Hulk television series back in 1989, Stan Lee appeared in most Marvel movies all the way up to Thor: Ragnarok, and a Business Insider interview.

Some cameos just consisted of him staring off, while others got creative and are really funny.

My personal favorite is as the janitor listening to headphones in The Amazing Spider-Man 2 while a fight scene is going on around him.

Rest easy, good sir. What's your favorite Stan Lee Cameo?
