Apple A Day

An apple is to a doctor as garlic is to a vampire. However, doctors don't seem to be out to get your blood - though they will happily take it off you if you volunteer. Also, apples are red like blood. And apples, just like blood, are important for your health. The words apple and blood also have the same number of letters. Wow, look at these things I can relate to each other for no apparent reason and for no particular purpose. Just remember to hurl those apples good and hard.
