Yes, that’s ‘Live Long and Prosper’ as in Star Trek as in Star TRAK, Pharrell’s production outfit, however, I intended for Pharrell to do it with me. He did not. In fact, he hit me with the “Hey, it’s J3!” finger point right back at me. I guess he’s been to THEROOTDOWN before. So I look like the moron, StarTrek ubergeek throwing the \\//, Definitely not one of the greater moments in rap hand history.
