The Plank (1967)

Two workmen (Eric Sykes & Tommy Cooper) whose individual aptitude is nil & their mutual aptitude chaotic , are employed laying floorboards of a house . The floor is completed except for the last plank , one of the workmen Sykes has sawn it up & used it for fuel in the fire place of the unfinished house . They set out to get a replacement plank from the local wood yard . This they intend to transport on the top of a small & battered old car . The plank with a surprising independence for an inanimate object , becomes detached from the car , & the large workman Cooper goes on foot to retrieve it .
