This is the seciond time the Holderness family has gone viral in the last year, and their follow up to the YouTube hit '#XmasJammies' is just as brilliant.
Their new song is a parody version of the 90's Sir-Mix-a-Lot rap, Baby Got Back, restyled as Baby Got Class- a song about getting ready to go back to school.
Singing about how they "like like big busses and I can't deny!", the best part is that the Holderness clan genuinely look like they are having incredible fun making it.
The finish off their video with a dedication "to the amazing teachers who take care of our kids all year and don't make enough money."
