Nurse Jenny

Two doctors were in a hospital hallway one day complaining about Nurse Jenny. "She's incredibly dumb. She does everything absolutely backwards." said one doctor. "Just last week, I told her to give a patient 2 milligrams of Percocet every 10 hours. She gave him 10 milligrams every 2 hours. He nearly died on us!"
The second doctor said, "That's nothing. Earlier this week, I told her to give a patient an enema every 24 hours. She tried to give him 24 enemas in one hour! The guy nearly exploded!"
Suddenly, they hear a blood-curdling scream from down the hall, "Oh my gosh!" said the first doctor, "I just realized I told Nurse Jenny to prick Mr. Smith's boil!"

Hubble Space Telescope

In 1990, the $2.5 billion Hubble Space Telescope was deployed in space from the Space Shuttle Discovery into an orbit 381 miles above Earth. It was the first major orbiting observatory, named in honour of American astronomer, Edwin Powell Hubble. It was seven years behind schedule and nearly $2 billion over budget. In orbit, the 94.5-in primary mirror was found to be flawed, giving blurred images and reduced ability to see distant stars. However, correcting optics were successfully installed in 25 Dec 1993. The telescope 43-ft x 14-ft telescope now provides images with a clarity otherwise impossible due to the effect of the earth's atmosphere. Instrument packages capture across the electromagnetic spectrum.
