Another one from the mind of my little 13 year old sister.
Song: Break on Through (To the Other Side)
Artist: The Doors
Actual Lyric: Break on through, to the other side...
Misheard Lyric: Right on to, to the other side...
Story: We were talking, and she started singing it, and I chuckled to myself, she asked why, and I corrected her lyrics. We both laughed for minutes on end.
