Sneaky End Credits

For whatever reason, I decided to watch or fast-forward through the entire end credits of "Iron Man 2." I get to the end and there is a 45 second clip. I'm not a comic book guy and I don't really understand "Iron Man" and "The Avengers," so I went to the IMDB for some clarification. Then I thought, I wonder if they pulled the same stunt at the end of the first "Iron Man?" Sure enough, they did. But I'm not going to spend the money to rent the movie just for 45 seconds. Thankfully "YouTube" had me covered.
