I had a friend (I swear it was a friend....) who thought the lyric in the song "Love Lifts Us Up Where We Belong" by Joe Cocker and Jennifer Warnes was really "Her lip goes up when we're alone." What a dumbass!
A childhood belief about misheard lyrics

others believed things like this
- In the song "We're going to Ibiza", my friend thought they said "we're going to eat pizza"!— Smaranda
- When I was little, my dad had a friend named Scott. I thought my dad's friend was the king of Scotland— Uhhh....
- I used to believe that the B-52's song "Love Shack" was actually "Love Shark!"— Natalie
- when I was a child I had never seen Jennifer Lopez written down so I thought her name was Jenny Ferlopez x)— Cath
- I used to think the song "love the one you're with" was called "love the one, your win. — Glowworm
- My friend's mom told my friend's little sister thatI when a dog died, it went to a retirement home.— ellen
