DJ Jazzy Jeff and the Fresh Prince's 'Summertime' is probably their most popular track out of their discography and it's easy to see why -- it's the perfect rap song. The accompanying video is just as fun as we see Jeff and the Fresh Prince (aka Will Smith) enjoy a backyard barbecue party with friends and family. Elsewhere, we see the duo cruising around their hometown of Philly and checking out the city and the fly ladies. This is the definition of summer madness.
