We'll get back to real news in a little. First, here's a bit of levity:
There is a picture from the picket lines on Monday that had Daniel Strauss, who tweeted it, saying, "Civility has disappeared in Chicago Teachers Union protests."
The sign was written in all caps: "RAHM EMANUEL LIKES NICKELBACK."
Nickelback, if you're not of that persuasion, is a popular Canadian rock band, which is not entirely unfamiliar with this kind of controversy. Back in 2011, Detroit Lions fans actually started a petition to have the band removed from a half-time show.
