My father, as a young boy, misunderstood some of the lyrics in Roger Millers 'King of the Road':
Actual words: 'Trailer for sale or rent...'
He heard: 'Trailer for sailorettes (as in, female sailors!)
A childhood belief about misheard lyrics

others believed things like this
- I was always afraid of trailer parks because I though that is where tornados came from.— Evan
- I believed that the ladder on the back of a trailer/rv led up to a swimming pool.— marilese
- Actual lyrics: "I've never been your beast of burden"
My lyrics: "I've never been your big suburban"
— Big Suburban - When I saw signs stating "Lots for sale" I thought it meant that there was a lot for sale.— Robin
- My buddy used to think that when Steve Millers sang "Jungle Love" he was actually saying "Chug-a-lug" — Harold
- I used to think Elvis' "I'm All Shook Up" was "A Mushy Cup". How sad of me to confuse the lyrics of a king...— Sad, Sad, Girl
