Tina Fey made her 20th, and final, appearance on the Late Show with David Letterman last night and really brought the heat. After Letterman tells her she looks wonderful, Fey reveals that this will be the last time she wears a fancy dress on a late-night talk show, and that she's always made a special effort to get dressed for Dave alone. And apparently this goes for the personalized "Bye Dave" shapewear Fey's wearing under her fitted dress, which she strips down to for a special send-off. It's awesome.
Letterman's final Late Show show airs May 20th.
