Heard about this one from my dad --
My parents were watching one of those "singing bee" or "don't forget the lyrics" shows on TV, and "Lucy in the Sky with Diamonds" was the contestant's song.
The lyrics "a girl with kaleidoscope eyes" come up.
My mom remarks "Oh, I didn't realize those were the words.." So my dad asks what she thought they were, and she answered:
"The girl with colitis goes by"
My dad about died laughing after hearing that one.
