From the Journal's Day Watch:

An arbitration panel today reinstated Cedarburg High School science teacher Robert Zellner, who was fired by the school district after it discovered he had viewed pornographic material on his school computer. School Board President John Pendergast said the arbitrator determined that the firing was improper because the school district had only reprimanded another teacher who had viewed stock quotes from a school computer. The three-arbitrator panel's written decision was not immediately available.

Porn... stock quotes... yeah, those are pretty much the same.  He was probably only looking at the money shot anyway.
