Comparing apples to oranges. They both grow on trees, they both have seeds inside (except for the hybrid oranges), they are edible and tasty, they both produce a good juice for drinking, they are nutritious, they are both sort of round. I'm thinking apples and mailboxes might be a better analogy if you're talking about two things that aren't alike.
