We had a CO play "Another One Bites the Dust" by Queen during a circuit assembly. He was trying to demonstrate the dangers of "backward masking", the idea that bands intentionally recorded messages only understood when the (vinyl) record was played in reverse.
After playing it forward, he then played a recording of the same clip, backward.
He told the audience, "now listen - they clearly say 'decide to smoke marijuana' ".
I'm glad he told us in advance, because to an unprepared ear, the recording sounded more like "dgrtvdf sowooort maggitorushssss".
But hey, if the CO says it says "decide to smoke marijuana", who am I to deny it?
