Quantum Leap

Quantum Leap is an American science fiction television series that ran for 95 episodes from March 1989 to May 1993 on the NBC network.

The plot involved scientist Sam Beckett (Scott Bakula) leaping to various points in time, usually constrained within the period of his own lifetime.


The show, which crosses a number of themes, including science fiction, family drama, comedy, social commentary, and nostalgia, won a broad range of fans. Sam occasionally has minor encounters with celebrities such as Buddy Holly and Michael Jackson as youths, helping to inspire their eventual fame (an example of a type of predestination paradox).

One of the series' most popular elements was that at the end of every episode Sam would leap into the next person, giving viewers a teaser of the following episode's installment. As part of a running gag, Sam would leap, and in awe of his new surroundings / circumstances would utter the catch phrase "Oh boy!"
