I was helping Reuben with his bath. We played knock, knock jokes for a while. Then he started asking questions.
"Where does water come from?"
"Well, hydrogen atoms and oxygen atoms..."
That wasn't the answer he wanted so he interrupted, "Where do pipes come from?"
"Factories use metal and plastic to make tubes, and then..."
Unsatisfied again, "Where do baby birds come from?"
"A mommy bird, and a daddy bird fertilize an egg..."
"NOOO!!!" he shouts, "THEY COME FROM HEAVEN!"
