Nothing worse than having to explain the joke, but here goes a breakdown of what you put in quotes:
1. Creates a "point A to point Z" connect-the-dots relationship with The Hawks by making the ancient reference of Pearl jam to Mookie Blaylock.
2. Tickles the nostalgia gland by making a compliment to Mookie/Augmon being underrated...on NBA JAM. A cartoon basketball video game that featured flaming balls and Bill Clinton as an unlockable character.
3. Throws in obligatory Celtics love with the Barros/Montross reference (HA HA! I AM SUCH A HOMER AND YOU ALL HATE IT!)
4. Combines Pearl Jam (the entire band, mind you) with hansen and then throws Courtney effing Love on top of it to basically slap you on the head and say (I AM KIDDING), because nobody would ever take that seriously.
About the only thing he could have done to be a little more obvious would have been to substitute Chris Cornell for Coutney Love and said that not only are the Sonics back, but so is Temple Of The Dog!
I guess next time he should pretend he is hitchhiking with a rubber thumb?
