You know the song "Eighteen Wheeler", by Alabama? My little brother used to belt out with all his heart instead of "Eighteen Wheeler", "Raging Weiner". ...that's what he thought it said.
A childhood belief about misheard lyrics

others believed things like this
- The song called heart of glass mixed me up as a kid. I heard "Heart and ass". — oops
- I thought Albania was the state of AlabamaAnon
- I thought the song "Party Time" by Moby was actually saying "heart attack" (this was before I knew the title)— Elviessa
- I used to think that Albania and Alabama were the same place.— Not me
- I used to think that when people had heart attacks someone came and stabbed their heartAnon
- I used to think that if you eat pig heart, you could grow another heart and be twice as healthier. Anon
