The AP has chosen Tina Fey as their Entertainer of the Year, and I couldn't agree more. Among other laudatory things they had to say about this decision, the AP describes Fey as, "She is the epitome of the smart kid coming out on top for once."
Nice one guys. Anyway, this is a choice by the AP that I think really fits. Fey has been around for quite some time doing some remarkably excellent comedy even in difficult circumstances (read: the SNL cast over the past few years) but this year she really blew up. The existing success and hilarity of 30 Rock certainly laid a good groundwork, but then along came a... well... yeah, you betcha, set of circumstances that might as well have been out of a story book. (remember that fake movie trailer? Ok... Tina Fey didn't make that but still...)
Anyway, good choice AP. I agree.
