When I find them I pour a little olive oil into the entrance of the hole. Then I anoint the head and nose of each sheep with the same oil and allow them to graze.

T-Bag swings his shovel in the hole while the rest of the men pour the concrete rubble behind the newly lain sheetrock.

After finishing the mould, we can design the pour system of mould, the trough of exhaust and overflow and localization hole, etc.
