Does Any of This Sound Familiar?

Has anyone besides me noticed that Barak Obama is taking a cue from the Chris Rock movie "Head of State" for his speeches out on the campaign trail? His "that ain't right" bit comes straight from the movie. I can't decide which is more sad, a candidate for President who uses a theme from a comedy movie as his own; or a bunch of brainless idiots who cannot recognize what he is doing, or if they do, they don't realize how pitiful this is!

Here's the clip from the movie...
Be WARNED... There is some improper language in this clip. If you don't want to hear it, don't play it! Don't get mad at me!
