The dance video is hilarious. The people from PwC are really变态 (bt - a slang term that can mean strange or perverted in this context).
Note: The term "BT" or "bian tai" can have strong connotations, and its translation can vary based on context. If you'd like a more appropriate or toned-down version, let me know! For instance, it could be translated as "weird" or "strange" depending on the intended meaning.
