Defective nails...?

Two guys were doing construction on a house. One of them who was nailing down siding would reach into his nail pouch, pull out a nail, and then either toss it over his shoulder or nail it into the siding.

The other guy, figuring this was worth looking into, asked, "Why are you throwing those nails away?"

The first guy explained, "If I pull a nail out of my pouch and it's pointed towards me, I throw it away 'cause it's defective. If it's pointed toward the house, then I nail it into the siding."

The second guy was outraged. He yelled, "You moron! The nails pointed towards you aren't defective! They're for the other side of the house!"

Sir Ronald Ross

Died 16 Sep 1932 at age 75 (born 13 May 1857). English physician, bacteriologist and mathematician who locatedthe malarial parasite in the gut of the Anopheles mosquito, identifying it as the disease vector.For this discovery he became the first British Nobelist, when he was awarded the 1902 Nobel Prize for Physiology or Medicine. His study of malaria began in 1892. By 1894 he conducted experiments in India to determine the validity of the hypothesis of Alphonse Laveran and Patrick Manson that mosquitoes spread the disease. It took two and a half years' effort before Ross succeeded in elucidating the life-cycle of malarial parasites in mosquitoes. In later work, in West Africa, he also determined the mosquito species carrying the deadly African fever.«
