I used to sing a LOT of songs wrong: "Take your pants down and make it happen" instead of "take your passion" (Flashdance theme)
"Silence like a casserole" instead of "cancer grows" - makes more sense doesn't it? (Sound of Silence)
Also thanks to my dad who fanices himself a bit like Weird Al: "There's a bathroom on the right" (Bad Moon on the Rise)
"I fought your ma and your ma won" was a lot more believable to me than "I fought the law and the law won"
A childhood belief about misheard lyrics

- CCR's Bad moon on the Rise, I swear it sounded liket they were singing, "There's a bathroom on the Right"— SMC
