"The Warning" is a song hinted at in PDF lyric sheets of With Teeth. The song's lyrics were not legible on the PDF. It is not known if it even was recorded or not, along with "My Dead Friend," "Message To No One," and "The Life You Didn't Lead," the latter two also hinted on various posters and PDFs. "My Dead Friend" was hinted at during an interview pre-With Teeth.

When the 2019 Definitive Edition vinyl of With Teeth was released, the PDF was re-created as part of the packaging. Lyrics to "The Warning" were made legible and it was finally revealed that "The Warning" from Year Zero has its origins in the track from the With Teeth sessions.

Interestingly, the line "celebration of ignorance" was later used in "Ahead Of Ourselves" from Bad Witch.

Lyrics

You can take this as a warning You can take this as a sign He is already among you Waiting for his time And it is coming Yes indeed A celebration of ignorance Self-importance and greed The virus will eat the host The virus will eat the host Your time is tick tick ticking away Your time is tick tick ticking away And you won't do a thing It's already over Tick tock Tick tock
