This week's 30 Rock series finale marks the end of an era, but instead of mourning, let's celebrate the show and look back at an incredible seven seasons. One of our favorite hallmarks of 30 Rock has been its slew of pretty incredible guest stars and the star power its been able to attract. From Olympians, musicians to Hollywood A-listers, the set of the show has really seen it all. Let's take a look back at over 30 of our favorite celebrity guests who made very special appearances!
