Crazy Man From China - song lyrics

My brother, Al, is four years older than I.  When we were young we'd sing the craziest songs.  I don't know where they came from because I've tried googling the lyrics and found nothing.  Was he clever enough to compose them himself?  I haven't a clue.  Here is a song we used to sing and I'm not sure all the words are correct or in the correct order.

Have you heard this one?

Mama told me to answer the door

But I didn't wanna.

I answered the door

He fell on the floor

The crazy man from China.

Mama told me to give him a drink

But I didn't wanna.

I gave him a drink

He ate up the sink

The crazy man from China

Mama told me to put him to bed

But I didn't wanna

I put him to bed

He hung off his head

The crazy man from China.

Mama told me to turn off his light

But I didn't wanna.

I turned off his light

He kissed me goodnight.

The crazy man from China.

Mama told me to take him to school

But I didn't wanna.

I took him to school

He acted like a fool.

The Crazy man from China.

Mama told me to take him to church

But I didn't wanna.

I took him to church

He ripped off his shirt

The crazy man from China.

Mama told me to bury him deep

But I didn't wanna.

I buried him deep

He stuck out his feet.

The crazy man from China.

Mama told me to cut off his feet

But I didn't wanna.

I cut off his feet

They ran down the street.

The crazy man from China.

And when I was young and silly I made this last line up.

Mama told me to shut up my mouth

But I didn't wanna.

I shut up my mouth

My teeth ran down south

the crazy teeth from my mouth.

Has anyone else heard this?  The first time I remember him singing it was probably around 1969.  Were we the only strange song kids back then??? lol
