I feel like I'm half these things

This mailbox is mine And this triagonal sign That blue balloon The month of June They're mine, mine, mine, mine, mine Ziggy's sweets are mine That birdie's tweets are mine The city streets Both your feet They're all emphatically mine It all belongs to me Everything that I see North, south, east and west I caress it, 'cause I possess it I'm Stingy and it's mine And this instrumental lick is also mine The floor and ceiling are mine All your feelings are mine You always knew it That's all there is to it It's mine, mine, mine, mine, mine That's what I said It's mine
