The addition of a weekly guest host was the most notable difference of season two, the only season of "Mad TV" to feature one. Although every season has had several guest stars, season two's guest stars were referred to as "hosts" and appeared in nearly every sketch. Every episode had a new host, where as in other seasons, not every episode had a guest star and the guest star usually only appeared in a few sketches. The guest host format was similar to their main rival "Saturday Night Live"'s, but "Mad TV" ended this format after season two (though later seasons would have special guest stars who appeared in sketches or did monologues).
