Cover art for Plan B lyrics by Five Iron Frenzy

Moldy bread has ergot alkaloids and was the cause of "St Anthony's Fire"- a "divine state" which is actually a close relative to an LSD experience.

Sure I don't think that's what FIF is getting at, but as Pentecostals I wouldn't think St Anthony's Fire is too far from their realm of knowledge.
