.... or the wailing of the operator when he realizes he put the carriage 
control tape on backwards of did not put down the brushes, its amazing

I have been in rooms where they had a box of earplugs at the door, but 
that came later in my field service rep days we where told that the

that is still in field service that now has hearing aids that are paid 
for by the company.
