Tina Fey is no stranger to the late show. The comedian turned actor has been a guest on David Letterman’s iconic late-night TV program about 20 times since it premiered in 1993. Now, Letterman only has a little over a week before his late-night career comes to a close, and he retires. Fey wanted to show Letterman just how much he means to her – and the rest of his audience – so she decided to close her final appearance with something special – **you’re not going to believe the gift she gives him to say goodbye.**
