If you listened to the show (and had a sense of humor) you'd know that just a couple of weeks ago, Rush was joking about his brother wandering the streets of Cape G naked.
Thus: funny.
Get a life. I happen to love Rush, and his brother.
I've been listening to Rush since '89, but he is nowhere near as good as he once was, so I don't listen all of the time, as I used to. I guess I missed his earlier reveries about his meandering brother, but I heard it today.
Even when Rush said, it wasn't really "funny", but hey....whatever tickles your funny-bone.
