It's a hot Summer day and Jake and Harry are in a ditch digging away. Meanwhile, Ralph is up under the shade of a tree sipping on a cool drink.
Jake asks Harry, “Why are we down here digging in the hot sun while Ralph is being cool up there?”
Harry says, “I don’t know, I’ll go ask him.”
Harry goes up and asks Ralph, “Why are you up here in the shade drinking a cool drink and Jake and I are in the ditch digging in the hot sun?”
Ralph says, “‘cause I’ve got smarts.”
“What do you mean?” asks Harry.
Ralph puts his hand in front of the tree and says, “Hit my hand as hard as you can".
Harry swings his fist at Ralph’s hand. Ralph moves his hand and Harry hits the tree, hurting his hand.
Ralph says, “I knew to pull my hand away, that’s called having smarts.”
Harry goes back in the ditch. Jake asks, “What did he say?”
Ralph says, “It’s ‘cause he has smarts.”
“What's that?” Jake asks.
Harry puts his hand in front of his face and says “Hit my hand!”
