I remember this song...we sang it in school in the 70's...goes like this....

A chinese man came knocking at my door, knocking at my door, knocking at my door
A chinese man came knocking at my door. My oh-oh my.

I opened the door and he fell on the floor, fell on the floor, fell on the floor.
I opened the door and he fell on the floor. My oh-oh my.

My mother told me to give him a drink, give him a drink, give him a drink.
My mother told me to give him a drink. My oh-oh my.

I gave him a drink and he fell in the sink, fell in the sink, fell in the sink.
I gave him a drink and he fell in the sink. My oh-oh my.

---Then it continues with my mother told me to take him to bed.....

continuing with i took him to bed and he fell on his head...my-oh-oh-my.

My mother told me to take him to church....
I took him to church and he lost his shirt...my-oh-oh-my

....hope this brings back good memories...It does for me :)
