List of guests
The show occasionally had guests on, especially in early 2015 when they experimented with having various YouTube personalities and others join for an episode.
For our purposes, "guests" are unique from "hosts" or "guest hosts". A guest is on for single episodes with both Day siblings hosting and are generally introduced as guests. Guest hosts assume hosting duties and fill in for multiple episodes while one or more Days are absent.
