An Italian, an Irishman and a Chinese fellow are hired at a construction site.

The foreman points out a huge pile of sand and says to the Italian guy, “You’re in charge of sweeping.”
He then jabs a thin finger at the Irishman, “You’re in charge of digging.” Finally, he turns to the Chinese man, “And you’re in charge of supplies. Now, I have to leave for a little while. I expect you guys to make a dent in that pile.”
Two hours later, the foreman returns to find the pile of sand untouched, and the Italian and Irishman standing nearby. “Why didn’t you touch it?” he says. The Italian looks at him. “We didn’t have a broom or shovel. You said the Chinese guy was in charge of supplies, but he disappeared and we couldn’t find him.” Annoyed, the foreman storms off to find the errant Oriental.
Just then, the Chinaman leaps from behind the sand. “Supplies!” he yells.
