Why do white guys try so hard to be down?

Its this white guy I work with well it seems like he likes me. Well anyway he's a bagger and Im a cashier. A customer came through my line and he gone say damn thats my favorite drink. I love me some grape kool-aid. I almost laughed my @ss off at him. I mean it was funny as hell. Why is he trying so hard? I mean I would like him if he just was himself. I don't even like kool-aid at all never have.
