Rapper's Math Skill

Hey, listen up, buttercup. This joke is all about wordplay. See, rappers are known for their "flow," which is how they rhyme and keep the rhythm in their rap. But "flow charts" are also diagrams used in math and computer science to show steps in a process. So the joke is saying the rapper is good at math because he has a lot of "flow charts," get it? You probably don't 'get it' considering you are the type of person that probably claps when the plane lands, and enjoys pineapple on pizza. Dummy.
