It’s always a delight to see Allison Janney on The Late Show. Can’t you just see the white light bouncing off of the tissue she’s holding in her lap on her eyes? She talks about her new projects (Tallulah) and her old ones (long live C.J. Cregg!), but let’s cut to the chase and get to the kissing. That’s what the people want! Janney and Colbert do a dramatic reading of Bon Jovi’s “Bad Medicine” — a reprisal of their bit when they did a dramatic reading of Foreigner’s “Hot Blooded,” but this time with more smeared lipstick. Can I get a cigarette?
