I don't know why he doesn't play "ooh, hey buddy" anymore either. He will say it when callers reference it, but I haven't heard the drop once. Maybe it was contractual or something....
I know this isn't a drop, but the past few days with "Brain" doing rapid fire have been hilarious. You can hear JJ and Matty laughing in the background.
Also, Matty saying "I get Karate Kid and you get a bangin' beat?" to JJ when they all had songs after their names.
