I don't really get Seth McFarlane's riff at the Oscars, or why it was funny. Female nudity in film is nearly as old as the industry itself. Moreover, in the era of the Internet and easy-access porn, the routine was dated.
And here is something darker. Katie McDonough points out that Seth McFarlane's shout-outs freely mixed rape scenes and sex scenes, and real-life violation:
[Scarlett] Johansson isn't even on MacFarlane's list for a film she made. Instead, she made her way into the song because of a real-life invasion of privacy, where her nude photos were stolen from her phone and leaked to the Internet. That is an actual, not fictional violation, and MacFarlane played it for laughs.
That aside, this is really just a continuation of the idea that everything from adultery to rape somehow belongs under the heading "sex scandal."
