My sister used to think that the Blues Travelers song "Run-around" started "Hooked by a reel at a fishing party" instead of "Once upon a midnight dreary"
A childhood belief about misheard lyrics

others believed things like this
- when i was little i asked what time midnight mass started.
i honestly had no idea.— what time?? - I thought the song "Party Time" by Moby was actually saying "heart attack" (this was before I knew the title)— Elviessa
- if you stand on your nose and sing the blues you wont get hiccups for a month.Anon
- I used to to believe that all adults went to bed at midnight.Anon
- I used to belive all grown ups went to bed at midnight.Anon
- I used to believe that all Street-Lamps were turned off at Midnight.Anon
