The word of the day is jocose:
1. Of persons, or their dispositions, etc.: Full of jokes: given to joking; playful, sportive, waggish.
2. Of speech, writing, or action: Of the nature of a joke, or characterized by jokes; spoken, written, or done in joke; playful in style or character. (OED)
"George Roy Hill is a “sincere” director, but [William] Goldman’s script is jocose; though it reads as if it might play, it doesn’t, and probably this isn’t just Hill’s fault. What can one do with dialogue like Paul Newman’s Butch saying, “Boy, I got vision. The rest of the world wears bifocals”? It must be meant to be sportive, because it isn’t witty and it isn’t dramatic. The dialogue is all banter, all throwaways, and that’s how it’s delivered; each line comes out of nowhere, coyly, in a murmur, in the dead sound of the studio."
