A building contracter hires an Englishman, an Irishman, and a Chinaman. He gathers them all in his office and tells each of them their jobs. The Englishman to shovel a pile of sand. The Irishman has to take the sand in the wheelbarrow to the truck. The Chinaman is in charge of supplies.
The boss comes back two hours later and he sees the Englishman and the Irishman having a cup of tea. ''So have you done the work then?'' he asks. ©JOKEDEMO.COM

The workers both shake their heads and tell him that the Chinaman didn't give them a shovel or a wheelbarrow. The boss is infuriated by this and asks the workers if they have seen the Chinaman, they tell him they thought they saw him going toward the truck. So the boss sets out towards the truck and just as he is getting close to the truck the Chinaman jumps out from behind a wall and yells, "SUPPLIES!"
