Just a Button

The show Seinfeld began and ended in the exact same way. In July of 1989, the show about nothing started with the two characters George and Jerry discussing the correct placement of a button on George's shirt. The show successfully made it through nine seasons on NBC and held true to its claim to being a show about nothing. On May 5th, 1998 George and Jerry ended the show with a discussion that was almost word for word the same as the beginning about where George should place the button on his shirt.
