Like An 's' From Missis-Ippi

Look, It's like this... I keep in touch with you, Because I love you. A concept you still don't understand. You are an external liver. Everything 'real' to you... Has to have a price tag on it! It's not that I don't have anything to do, That I keep in touch with you. I have no problem finding use for my time. And... I don't have to have a dime in my pocket. If you want that proven... Just give me the word. A letter or a clue. And I'll be missing in action! Like an 's'... From Missis-ippi. Trust me, I have my own set of values.
