I used to believe that the lyric to Anarchy in the UK by the Sex Pistols was
'I wanna destroy Piss supply'
the actual lyric is 'I wanna destroy passerby'
A childhood belief about misheard lyrics

others believed things like this

- A common misheard lyric in BMTH’s ‘Shadow Moses’ is “THIS IS SANDPIT TURTLE!”— Oli
- My sister just recently realized that the lyric "more than a woman" wasn't 4 letter woman!— Anne
