Kevin Smith, Tara Reid, and Michael Rooker go to The Stan Lee school of cameo acting
Stan Lee, of course, made his name as the original creator of many comic book legends - including the X-Men, Thor, Spider-Man, and the Fantastic Four.
As a result, he's made a cameo appearance in almost every Marvel superhero film since the year 2000 - from the original X-Men to the new Age of Ultron. He's an expert at being a minor character.
So he shows the kids how it's done at Stan Lee's Cameo School of Acting.
The short slot also features director Kevin Smith (Clerks, Dogma), Tara Reid (The Big Lebowski, Sharknado), Michael Rooker (Guardians of the Galaxy, The Walking Dead), Jason Mewes (Clerkes, Jay and Silent Bob), and Lou Ferrigno (the original Incredible Hulk).

That's a pretty good set-up for a skit that is paid for by Audi, as the car Stan Lee drives. That's a pretty subtle advert for all the dollars that were probably paid out.
Personally, the best bit is when Stan stands on his soap box. Heh.
