Will Smith dropped by 'Late Show,' and dropped some rhymes as well. On his way to the desk, he grabbed the microphone from Paul Schaffer and broke into a few verses from his hit, 'Summertime.' He explained that he sometimes just feels the need to rap. He stayed in a jovial mood, even when Letterman brought up those rumors about Will's son, Jaden. The rumors are that Jaden wants to be legally emancipated from his parents, Will and Jada Pinkett Smith.
