The Onion actually apologizes.
There actually is a line that even humor can't cross, and this is evidence of where that line is:
We get how this is a joke, but it's aimed at a particular child. Quvenzhané Wallis is the 9-year-old who had a Best Actress nomination for "Beasts of the Southern Wild." Wallis will also star in the new film version of "Annie," taking the part that Willow Smith declined on the ground that she preferring just being a kid.
Speaking of sex jokes aimed at young girls — and speaking of girls named Willow — this reminds me of the way David Letterman had to apologize for making a joke about Willow Palin. (To his credit, Letterman was under the impression that he was making a joke about Bristol Palin who was 18 at the time.)
