THE MARY MATALIN/JAMES CARVILLE REALITY SHOW. Would you want them in your high school? I think it sounds like a cool show, and I’d be tempted to say yes, but I think the proper answer for school authorities is no. If you know anything about reality show editing, you know it’s not fair to the real individuals who produce the footage and who often don’t understand how they are providing the material for their own humiliation. If you don’t know what I’m talking about — or if you just want to see the greatest TV comedy of all time — get the DVD of “The Comeback” and see what happens to our darling (fictional) character Valerie Cherish.
