dumb little joke test

There was this Spanish guy, this Korean guy and this Russian guy all working for the same construction company.
At the beginning of the day the boss comes out and says to the Spanish guy, "You're in charge of the cement."
Then he said to the Russian guy, "You're in charge of the dirt."
Then he said to the Korean guy, "You're in charge of the supplies."
Then he said, "I'm gonna be back at the end of the day to check on your work. It better be good or you're fired." So they all go off to go get their work done.
At the end of the day, the boss comes back to check on their work. He looks at the big pile of cement and goes, "Good work," to the Spanish guy.
Then he looks at the big pile of dirt and says, "Good work," to the Russian guy.
Then he couldn't find the Korean guy so he asks, "Where the heck is the Korean guy?"
All of a sudden, the Korean guy jumps out from behind the big pile of dirt and yells, " SUPLIES!
