Clay Class is a joke that started when Brian and Justin did their breakdown of Lionel Ritchie's music video for "Hello". In the video, there is a moment where a man tells Lionel "Excuse me but, there's something going on in the sculpture class." Once Brian, Justin and Chatrealm heard it, this line transformed into "Some shit's goin' down in clay class!". Since then, this line has been turned into a catch phrase that can be used and altered whenever something extraordinary is happening.
