LITTLE YELLOW BIRD WITH A LITTLE YELLOW BILL

JUST PERCHED UPON MY WINDOW SILL

LURED HIM IN WITH A PIECE OF BREAD

AND THEN I SMASHED HIS FUCKIN HEAD

I first heard it a long time ago in a movie, but without the naughty word. I think.
Peace,
mangeorge

IIRC, it’s a marching cadence used by either the Army or USMC.
