A friend and sccharmschool member posted in her own LJ Why all the fuss over a first lady's bare arms? which attempts to answer the question.
I think she failed, so I posted The real reason everyone is nuts over Michelle Obama's arms because I figured I just had to get in on all this considering the theme of my blog.
She even failed to get which decade T2 came out, but at least Sarah/Linda does get a mention.
I figured I'd share it here and see what people think.
