A little parody I put up last night of the already legendary "smoking" promo by Herman Cain's campaign chief Mark Block (see the original here).

Also see Stephen Colbert's take (we went for the same joke, not surprisingly he did it better):

Letterman's take:

And possibly my favorite for sheer surreality, this offering from Tim Heidecker of "Tim and Eric Awesome" fame (via BoingBoing)

Am I missing any other good ones?
