"Saved by the Bell" was a popular TV sitcom in the United States that aired on NBC from 1989 to 1993 and led to TV series spin-offs and three TV movies. The show dealt with the adventures of a principal and a group of high school friends.

Stars of the original TV series were Mario Lopez, Elizabeth Berkley, Tiffani-Amber Thiessen, Dennis Haskins, Lark Voorhies, Dustin Diamond, and Mark-Paul Gosselaar.
