Stephen Colbert, since returning from vacation, has been on quite a streak. Last night, his conversation with Jerry Seinfeld was charming (and yes, as I predicted, Colbert served his guest some coffee). Tonight, I expect no less – well, no less charm. (Forget about the coffee.) Colbert’s guest tonight is Jeff Bridges (seen here from a previous visit), who, like Seinfeld, has worked very hard to make what he does seem effortlessly natural.
