These two
newfies are building a house. One
of them is putting on the siding. He picks
up a nail, hammers it
in. Picks up another nail, throws it away. Picks
up a nail, hammers
it in. Picks up another, throws it away. This goes
on for a while,
and finally his friend comes over and asks him why he is
throwing
half of the nails away.

He replies, “Those ones were pointed on
the wrong end.” The buddy
gets exasperated and says “You idiot,
those nails are for the other side
of the house!”
