Will Smith was on the Late Show Tuesday to promote his new movie Suicide Squad , but when Stephen Colbert 's house band started playing DJ Jazzy Jeff and the Fresh Prince's 1991 classic "Summertime" as the show went to commercial, the once and forever Fresh Prince was moved to get up and rap to the surprised studio audience. It probably wasn't spontaneous, but it felt spontaneous. Impromptu or not, it was a lot of fun and great reminder that "Summertime" has slipped into "underrated crowd-pleaser" status. Deejays, take note. (Full disclosure: TVGuide.com is owned by CBS.)
