they are burning

Pepito was hit by a car,
died, and went to heaven.
And everyone who goes to heaven has to work.
God went up to Pepito, and said:
Pepito, you are going to make babies.
Here is this wheel, and every time you turn it, a baby will come out.

For hours, Pepito spun the wheel at full speed,
then he started to get tired.
As he was slowing down,
a black baby came out…and Pepito replied:
Damn! I better hurry because they are burning!
