Another really funny joke?!

When NASA first started sending up astronauts, they quickly discovered that ballpoint pens would not work in 0 gravity!. To defeat the problem, NASA scientists spent a decade and $12 billion to develop a pen that writes in zero gravity, upside down, underwater, on almost any surface including glass and at temperatures ranging from below freezing to 300 C!. The Russians used a pencil!.Www@Enter-QA@Com
