The best fast food rap in the world, (I need a double cheeseburger and hold the lettuce, don't be frontin' son, no seeds on the bun, we be up in this drive through order for two, I gots a cravin' for a number nine like my shoe. We need some chicken up in here, in this dizzle, forizzle my nizzle extra salt on the frizzles. Dr.Pepper my brother, and another for your mother. Double double super-size and don't forget the fries.) Usually confuses drive through operators and can get them very annoyed. Best drive through joke since, "and then?". This rap will only be succesfull at a McDonalds and not any other fast food restaraunt.

Person 2: "I hope the manager didn't shoot him."
