Everything You Know Is Wrong is the eighth comedy album by the Firesign Theatre. Released in October 1974 on Columbia Records, it satirizes UFO conspiracy theories and New Age paranormal beliefs such as Erich von Däniken's Chariots of the Gods and claimed psychic Uri Geller, which achieved wide public attention by that time.

The four main characters are pictured on the album cover:

"Happy" Harry Cox (Phil Austin) — narrator of the album; purveyor of New Age fringe theories. Cox calls his followers "Seekers" and runs a recording studio he calls "Nude Age Enterprises" from his mobile home in a nudist trailer park located in the fictional town of Hellmouth, California (surrounded by the towns of Hooker and Heater). Although Cox is depicted on the cover and in the accompanying video as clothed, he apparently is a nudist, as Gary asks "Why are you naked?" when meeting him face-to-face.

Gary (Peter Bergman) — a teen-age "Seeker", member of a group who travel on the "Heavenly Bus".

Art Wholeflaffer (David Ossman) — nudist manager of the trailer park where Cox lives. Wholeflaffer is actually a nudist, as he is depicted as wearing only a visor cap and tool apron.

Nino Savant (Philip Proctor) — the "Great Mind-Boggler" who communicates with his audience "by sending directly from his mind to yours"; a satire of "psychic" spoon-bender Uri Geller. (Wikipedia)
