A couple of guys at the construction site come to see the boss.
"Boss, we have this beam, we can't get it in place. Not sure what to do."
The boss thinks for a second. "Ok guys, you won't believe this, but if you smack your head against the beam, it'll go right into place. Sounds weird but trust me, it will work."
The guys are skeptical, but hey, he's the boss. So they go and smack their head against the beam. They hit it hard, then harder. They get kind of dizzy. Finally they look at each other and go to see the boss.
"Boss, we hit our head against the beam. Hard. And a lot. I even got dizzy. The beam didn't move at all. What do we do?"
"Hmm," the boss says, rubbing his chin, looking off into the distance, deep in thought. "Here's what you need you do," he finally says.
"Go hit it harder."
