Lynn & Judy were doing some carpenter work 
on a Habitat for Humanity House.  
Lynn was nailing down house siding, 
would reach into her nail 
pouch, pull out a nail & either toss it 
over her shoulder or nail it in. 

Judy, figuring this was worth looking into, asked, 
Why are you throwing those nails away?' 
Lynn explained, 'When I pull a nail out of my pouch, 
about half of them have the head on the wrong end 
& I throw them away.' 
Judy got completely upset & yelled, 
'You moron! Those nails aren't defective! 
They're for the other side of the house!'
