Lumberyard

Jon's working at the lumberyard, pushing a tree through the buzz saw, and accidentally shears off all ten of his fingers. He goes to the emergency room.
The doctor says, "Yuck! Well, give me the fingers, and I'll see what I can do."
Jon says, "I haven't got the fingers."
The doctor says, "What do you mean, you haven't got the fingers? It's 1999. We've got microsurgery and all kinds of incredible techniques. I could have put them back on and made you like new. Why didn't you bring the fingers?"
Jon says, "Well, sh*t, Doc, I couldn't pick 'em up."

First Earth orbit by man

In 1961, Yuri Gagarin became the first man to orbit the Earth. His spacecraft, Vostok 1, had radio, television and life-support equipment to relay information on his condition. The flight was automated. Gagarin's controls were locked to prevent him from taking control of the ship, although a key in a sealed envelope was provided in case of an emergency. After e-entry, Gagarin ejected and made a planned descent with his own parachute. However for many years the Soviet Union denied this, because the flight would not have been recognized for various FAI world records unless the pilot had accompanied his craft to a landing. Gagarin died in a plane crash 7 years later.«
