White With Black Stripes?

Once there were two zebras. One zebra asked the other:
"Am I white with black stripes or black with white stripes?"

The other replied:
"Ask God."

That night before the first zebra went to bed, he prayed. God replied:
"You are what you are."

The zebra was confused by this, and the next day, he asked the second zebra what it meant. He replied:

"I gues you are white with black stripes, otherwise he would have said 'Yo is what yo is.' "
