Two zebras are talking and one asks the other, "Am I black with white 
stripes or white with black stripes?" The other replies, "Well I don't 
know. You should pray to God about that and ask him." So that night he did 
and God replied, "You are what you are." The next day he said to the other 
zebra, "I still don't understand what I am because God just said, You are 
what you are." The second zebra responds, "You must be white with black 
stripes or else God would have said, Yo is what yo is."
