St. Peter said he would have to ask God that question since he's the one that made him. So the zebra asked God, "God, am I a white horse with black stripes or a black horse with white stripes?"
God answered, "You are what you are."
The zebra left and came upon St. Peter and told him, "Well I asked God if I was a white horse with black stripes or a black horse with white stripes..."
"What was the answer," St. Peter asked.
"Well I still don't know. All He said was: 'You are what you are."'
"Well that answers it," Said St. Peter. "You're a white horse with black stripes."
"How do you know that?" asked the zebra.
"Well if you were a black horse with white stripes He would have said: "You is what you is".
Technically they’re black with white stripes. :)
