You can take from your shin
And put on your chin;
As long as it rhymes it's the same.

You can take from your hip
And put on your lip;
As long as it rhymes it's the same.

You can take from your rear
And put on your ear;
As long as it rhymes it's the same.

You can take from your toes
And put on your nose;
As long as it rhymes it's the same.

You can take from your bum
and put on your thumb;
As long as it rhymes it's the same.
