"Theorizing that one can time travel within his own lifetime, Dr. Sam Beckett led an elite group of scientists into the desert to develop a top secret project known as 'Quantum Leap'. Pressured to prove his theories or lose funding, Dr. Beckett prematurely stepped into the project accelerator...and vanished. He awoke to find himself in the past, suffering from partial amnesia and facing a mirror image that was not his own. Fortunately, contact with his own time was maintained through brainwave transmissions with Al, the project observer who appeared in the form of a hologram that only Dr. Beckett can see or hear. Trapped in the past, Dr. Beckett finds himself leaping from life to life, putting things right that once went wrong and hoping each time that his next leap...will be the leap home."

And some sad news. Our own network here, NBC, has canceled the television show Quantum Leap.
(Audience: Awwwwww....)
It was a good show, but it was ranked 82 out of a hundred shows. It was 82nd. It was 82nd. Boy, not only are we losing Cheers, our highest rated show, we're also losing Quantum Leap, our second highest rated show. This is terrible! It's terrible! Oh, man...
(Audience: laughter and applause)
(looks up into audience) All the NBC brass are here. I'll go get a job with Allstate in the morning.
