John Goodman‘s druggie jazzman offers a dismissive little riff during the road-trip section of Inside Llewyn Davis. He basically says jazz musicians are more expressive because they play more notes or chords than folk singers. I’ve seen Davis four times and Goodman’s bit didn’t register, but I suddenly cracked up when I heard it last night during…what, my fifth viewing? That’s what Coen brothers humor is sometimes. “Funny” doesn’t kick in like a Jay Leno joke. It needs to percolate.
