When we were little my sister used to think the lyrics to the Def Leppard Song were "Put your sheets away" instead of "Pour some sugar on me".
A childhood belief about misheard lyrics

others believed things like this
- in the song with the lyrics "take your passion" my sister used to always think it was "take your pants off"— Steped
- When I was little, I used to think my dad was in def leppard.— Ashley
- I thought that a "sugar daddy" was a father who let his kids eat all the sugar they wanted.Anon
- adding too much sugar to foods would give you "sugar worms"...
Anon - I used to believe that when cordial drink said 'sugar free' that you didnt have to pay for the sugar in it!— Grace Lyon New Addington
- My mum told me that if I ate sugar from the sugar bowl I'd get worms.— QueenB
