~ I'm an Acorn ~

I'm an acorn, small and round, lying on the cold cold ground
Everybody steps on me, that is why I'm cracked you see
I'm a nut [knock knock] I'm a nut [knock knock] I'm a nut [knock knock] I'm a nut
OR
Call myself on the telephone, just to hear my golden tone
Ask myself out on a date, pick me up at a quarter to eight
I'm a nut, I'm a nut, I'm a nut, I'm a nut
OR
Oh, wasn't it a bit of luck that I was born a baby duck
With yellow socks and yellow shoes, that I may go wherever I choose
Quack quack quack quack quack quack quack quack, quack quack quack quack quack quack 
(Brittony T says this is sung in a round with Gray Squirrel)
OR
I'm a little piece of tin, nobody knows where I have been
Got four wheels and a running board, I'm a Ford, oh, I'm a Ford
Honk honk rattle rattle rattle crash beep beep
Honk honk rattle rattle rattle crash beep beep
Honk honk rattle rattle rattle crash beep beep, honk honk!
