(Bing Crosby)

mule is an animal with long funny ears
he kicks up at anything he hears
His back is brawny and his brain is weak
he's just plain stupid with a stubborn streak
and by the way if you hate to go to school
You may grow up to be a mule

Oh would you like to swing on a star
carry moonbeams home in a jar
and be better off than you are
or would you rather be a pig

pig is an animal with dirt on his face
his shoes are a terrible disgrace
He has no manners when he eats his food
He's fat and lazy and [bad word] But if you don't care a feather or a fig
you may grow up to be a pig

Oh would you like to swing on a star
carry moonbeams home in a jar
and be better off than you are
or would you rather be a fish

fish won't do anything but swim in a brook
he can't write his name or read a book
to fool the people is his only thought
and though he's slippery he still gets caught
but if then that sort of life is what you wish
you may grow up to be a fish
(music)
a new kind of jumped up slippery fish

And all the monkeys aren't in the zoo
everyday you see quite a few
so you see it's all up to you,
you could be better than you are
you could be swinging on a star
