Somewhere on the DVd of The Incredibles is an easter egg that is an interview with the characters: that is, Mr. Incredible, etc & a RL interviewer.
How do I find this?
Any other good easter eggs to find?
The Incredibles Easter eggs.
Hmmm…if it isn’t an Easter Egg, where is it? 
Wiki says it exists.
Watch the sock puppet version of the movie. It’s almost as good as the original. (It’s listed in the Easter Egg link that **silenus ** gave.)
Yep, I’ve watched it on the DVD. I can’t tell you how to find it though, I’m at work now.
This is not an easter egg- the feature appears under the “Publicity” section of the “Behind the Scenes” menu on the second disc. Pixar appearently enjoys doing clips that can be used on the news to make it look like the characters are being interviews, since a similar feature appears on other Pixar DVDs as well.
As far as special features go, my favorite by far is the superhero files from the government. The audio clips are often hilarious.
