One day a boy and his father were walking through the woods when the son spotted some rabbit droppings.

The boy asked hid Dad, ''What are these Pop?''
''They're smart pills son,'' said his father.
''Eat them and they'll make you smarter."

So he ate them and said, ''Yuck...these taste like s**t!''

''See,'' said his father, ''you're already getting smarter!''
