For a couple generations now, the big reliable joke for Late Night shows is: “Republicans are stupid.” That joke right there used to bring down the house very consistently. But it’s not enough now. But they have nothing else.
For a while I would watch Leno’s monologue mostly just on Monday nights as I waited for ‘headlines.’ It seemed to center around a small collection of ideas ‘George Bush has a the mind of an infant’, ‘Brittish people have bad teeth’ and ‘Jennifer Lopez has a large butt.’
At some point his ‘comedy writers’ went on strike and Leno became funny again!
