Smart Pills

So a boy and his father were walking in the mountains one day when the boy looks down at the ground and says: "Hey dad, what are these little round things?"
The dad looks at his boy and says: "Well son, those are get smart pills. You take just one, and you'll be smarter."
The boy reluctantly picks up one and pops it in his mouth, seconds later he screams: "Dad, that tastes like shit!"

The dad says: "See, you're getting smarter already!"
