An Italian, an Irish man and a Chinese man all get jobs at a
construction site. The boss of the site walks up to the three
men, points at a pile of sand behind him and then pointing at
the Italian says "You're in charge of sweeping". He then points
to the Irish man and says "You're in charge of digging". Finally
he points to the Chinese man and says "You're in charge of
supplies." He carries on speaking "I'm going to be gone for a
while and when I come back I expect to at least see you guys
have made a dent in that pile".

The boss comes back two hours later to find the pile of sand
untouched, and the Italian and Irish man standing by. He walks
up to them and shouts "what the hell have you been doing for
the last two hours, and where's the Chinese man?" The Italian
tells him "you put us two in charge of sweeping and digging, but
we don't have a broom or a spade. You put the Chinese man
in charge of supplies, but he's disappeared." The boss looks
round and searches for the strange Orient. Suddenly when the
boss approaches the pile of sand, the Chinese man jumps from
behind the sand and yells "Supplies!"
