SEASON PREMIERE: Last week, 60 Minutes returned on CBS for the start of Season 47. That makes it the longest-running prime-time series currently running, but look which show is close on its heels. Two other newsmagazines are right behind 60 Minutes in the tenured department, but The Simpsons, now starting Season 26, is the longest-running scripted series in current TV history. It’s been around a long, long time, which makes it seem only natural that on tonight’s season opener, a familiar Springfield resident dies. Meanwhile, other characters are killing: Sarah Silverman, for example, guest stars, firing deadly zingers at a roast of Krusty the Klown.
