In its seven year run, at least 18 actors from "30 Rock" received Emmy nominations. That's a pretty mind-boggling figure. 
 
That includes stars Tina Fey and Alec Baldwin and Jane Krakowski and Jack McBrayer and Tracy Morgan, of course, but the bulk of the show's acting nominations went to one of the deepest guest-starring reservoirs in TV history. It's a group that included regular guests like Elaine Stritch and Chris Parnell and Jon Hamm, but was also highlighted by delightfully random appearances by movie stars, politicians, puppets and media personalities attracted by the show's spectacular writing and convenient New York locations.
