1 tree or wall
3 scouts

Two guys are working hard, shoveling dirt.

A third guy (the boss) walks over and stands around, looks at the work they've done, reads a paper.

Scout #1: Hey, Joe. How come we have to do all the hard work and the boss there gets paid more than we do?
Scout #2: I don't know. Maybe you should ask him.
Scout #1: Good idea.
#1 lays down his shovel and walks up to Boss.
Scout #1: Hey, boss, how come we do all the work and you get all the pay?
Boss: Because of 'Intelligence'.
Scout #1: Huh?
Boss: Here, let me demonstrate.
Boss places his palm flat against a tree.
Boss: OK, hit my hand as hard as you can.
Scout #1: OK.
As #1 hits the hand, the boss pulls his hand away so #1 slugs the tree and hurts his own fist.
Boss: You see, that's Intelligence. Now, get back to work.
#1 returns to shoveling.
Scout #2: So, what did he say?
Scout #1: He said it's cause of Intelligence.
Scout #2: Huh?
Scout #1: Here, let me demonstrate.
#1 holds the palm of his hand in front of his own face.
Scout #1: OK, hit my hand as hard as you can.
