 Episodes that have these errors in their sketch-of-the-day teasers include 297, 390, 1A, 8A, and 15A—sometimes the music started too late, ended too early, or played too long; sometimes the errors are negligible, with the teaser music only playing a fraction of a second longer than usual.For season six, because the teaser music was changed to a shorter, self-contained composition, these errors do not occur, with the exception of the teaser of 33B shown at the end of 32B (available on iTunes), where the teaser was accidentally "cut" by a fraction of a second.
