LOS ANGELES (AP) "The Big Bang Theory" has ended its 12-season run with some big changes for its band of lovable geeks.

The CBS sitcom aired its final two episodes Thursday in an hour-long finale that drew the series to a close after 279 episodes.

The episode featured a cameo by Sarah Michelle Gellar and a speech from Mayim Bialek's character, Amy, urging little girls to pursue careers in science while accepting a prestigious honor that was teased as a possibility during the final season.

The show ended as many of its episodes did, with the "Big Bang" characters, one of them now pregnant, eating Chinese food together.

The series leaves on a high as one of television's most popular shows, and has sparked the popular spin-off "Young Sheldon."
