An Italian, a Scotsman, and a Chinese fellow are hired at a construction site.
The foreman points to a huge pile of sand and says to the Italian guy, "You're in charge of sweeping." To the Scotsman, he says, "You're in charge of shoveling." And to the Chinese guy, "You're in charge of supplies."
The foreman then shrugs his beefy shoulders and says, "Now, I have to leave for a little while. I expect you guys to make a good dent in that pile of sand by the time I get back."
