Mike Konkoleski, a 10th grade math teacher at Eric Solorio Academy High School, was identified as the man behind the audacious assault on Chicago mayor Rahm Emanuel's character in the form of a protest sign declaring Emanuel a fan of Nickelback.

Emanuel's spokeswoman was forced to issue a vehement denial yesterday, saying her boss was in no way, shape, or form a Nickelback lover.

Micah Uetricht, who tracked down the incendiary instructor, says Konkoleski was not interested in being interviewed, but was more than happy to levy an even more contemptuous charge: That Emanuel also liked Creed.
