Once upon a time in China, lived two Chinamen.

One
named I cum and one named No cum.

No cum marry
pretty Chinese girl named No cum tu.

For velly obvious
reason No cum and No cum tu not have any children.

One day, no cum went out of town on business and
I cum came over and spent the night with No cum tu.

That night I cum came and No cum tu came too.

This
make both velly happy.

However about 7 or 8 months later, No cum see he
about to become father but he not know how come,
so when baby come, he named it, How cum u cum.

Of course, I cum and No cum tu know How cum u
cum came but to this day No cum not know how
come How cum u cum came!

Cum again?
