If you need a greeting for your Valentine's Day greeting, why not borrow from the great wordsmiths, The Barenaked Ladies.

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

 

Feel free to write it in a stanza form to make it look prettier as well

 

"If I were John, and you were Yoko,

I would gladly give up music genius

just to have you as my very own personal Venus."

 

Good luck!
