This is how I remember it from 1969 in Western NYS- and after seeing the other posts I have to laugh because we always said Pa instead of pie and it never made any sense to me-but most of these didn't anyway.....And I also can see a reference to the times-related to the bus being too black....

Ooh Ahh, Wanna piece of Pa
Pa too sweet
Wanna piece of meat
Meat too tough
Wanna ride a bus
Bus too black
Want my money back
Money too green
Make me wanna scream
"Your father's got a head like a submarine!"
