A couple of roofers are up on a side of a roof nailing on shingles.
As one is working, he pulls a nail out of the bag, looks at it, and
hammers it in. Then he pulls another nail from the bag, looks at it,
and throws it away. He looks at the next one and hammers it in.
After a few minutes of this, the other roofer asks, "Why are you
throwing out all those nails?"
He replies, "They put the head on the wrong end!"
"You idiot, those are for the other side of the roof!"
That was one of my grandfather\'s favorite jokes.
