The song "30-40 (Skit)" by JILLZAY is a humorous skit rather than a full-fledged song with a deep meaning or story. It features a conversation between two people where one person asks the other to make a wig for them. The lyrics start with the request to make a wig, with the person asking politely for it to be made. The other person responds by saying "not now" and suggests doing it in about 40 minutes or 30 minutes instead. There are also some lines about cleaning the bass (possibly referring to a musical instrument). Overall, the skit appears to be a light-hearted and playful exchange between two individuals discussing making a wig and making plans for when it should be done.
