Illinois’ disgraced and indicted former governor, Rod Blagojevich, isn’t exactly a stay-at-home kind of guy. This weekend, for example, he’ll attend a performance of the Second City spoof, “Rod Blagojevich Superstar,” where he “has been contracted to show up” to announce its extension and to participate in the post-show improv. The revue’s producer “wouldn’t discuss on the record what financial deal had been made with Blagojevich.”
