Stan Lee does a lot of cameos, and it's time for him to pass on the experience he's gained. At least in this short that Kevin Smith cooked up. Technically, the whole video is an advertisement for Audi, but aside from the fairly obvious product placement and the company logo at the end, you might never know.
What's more likely is that you'll spend the length of this video going "Hey, is that ____ from ____?"
Yes. I'm not going to spoil anything, but the answer is yes.
