Nailed it!

Watching these four construction workers sledgehammer a post with the precision of a Marine Corps drill team is oddly fascinating. You have to wonder how long it took them to get their timing down. And how would you like to be a new guy on that crew? Talk about pressure. The first day on any job can be tough, but it has to be especially difficult knowing that if you make a mistake, you're messing things up for three beefy dudes who swing sledgehammers for a living.
