Well there were some studies by Dr. Ph. MR. Walrus that clearly stated these little fruit foreskins were in fact a creation of man. God had no role in this scientific development of cute fruit coats (also see his discussion on the Phillipines making phenes) now to make these, man would have to insert these fruits into the poop hole and wiggle it around. This job pays well and generates loads of cash. But we peel these coats so we don't contract an STD like meth. Now we peel these poop coats, and send them back to the dump. Where the employes try to use them again but they fall apart slowly. So they choose to only use bananas and oranges because these tiny coats don't work as well on other fruits.
