Reasons why you wash grapes before eating them:
-They're coated in that white layer of dusty film
-Other people have touched them
-Some of them tried to escape during checkout and rolled onto the conveyor belt--the same conveyor belt a woman placed her baby on after smelling its diaper and gagging
-Eating unwashed fruit can give you diarrhea (You saw this on an episode of "The Doctors")
-It makes baby Jesus cry.
