In the song, "Lucy in the Sky With Diamonds", I thought the line went : ". . . the girl with colitis goes by." instead of the correct " . . .the girl with collidoscope eyes". I had heard of people having some kind of condition called colitis; but hadn't the slightest idea what it was. I held this belief until I was well into my teens.
