If i was John and you were Yoko I would gladly give up music genius,
just to have you as my very own
personal penis.

The story:

I was seven years old and enjoying this song in the car with my mother, and i told her, i like this song but there's a bad word. (Of course, penis is NOT a bad word, however, it's not something a seven-year-old should talk about)
Curious, my mother asked what swear word was in it, and when i told her, she started laughing and told me i was sadly mistaken.
