Usher's wife: "Hey Brian, what are you doing?"
BW: "Oh, I'm just sitting here in the chair with a golf club in my hand."
(then a few minutes of silence goes by)
BW: "Now there is no golf club in my hand."
(Wife looks over, noticing he had put golf club down. She goes back to strumming guitar, then looks over and notices he has picked the golf club back up.)
Usher's wife: "And now you have the golf club back in your hand."
(Brian looks at her and cracks up laughing.)
This plays like a scene written by David Lynch.
Doesn't strike me as anything more than Brian and Usher's wife goofing around in a non sequitur manner.
