i know what Turntable is sayin. if you take any adult and ask them this question, the answer will probably be Summertime.
but if you ask any teenager, they will more likely say Gettin Jiggy or MIB. trust me there's references to gettin jiggy wit it all the time and everyone has seen MIB. i think alot of teens know about Summertime too, but not as much as that about about GJWI and MIB
in conclusion, it's probably Summertime.
