A childhood belief about misheard lyrics

I used to have this obsession with the play Cats and used to sing the Jellicle Song all the time. My friend could'nt understand why I was singing a song about 'Jellycones' She thought I was singing about dancing cups of jelly.
And also she though "saying skimble where is skimble has he gone to hunt the thimble" was "saying skimble where is skimble he's up a tree". weird!
