Tina Fey only wears a fancy dress out of respect for David Letterman, and since he’s retiring, she unzipped Thursday.
“It’s very hard work, I don’t know if you’re aware of the contraptions under here — it’s almost medical,” Fey told Letterman.
“What am I going to put on a dress for Jimmy? That’s creepy. He’s like my brother,” she said about Jimmy Fallon.
James Corden won’t get the dress either: “I’m gonna wear like special underwear for James Corden? That’s not gonna happen.”
Fey then got down to it, and revealed a #LastDress undergarment that said “Bye Dave!”
“I don’t know what to say,” a flabbergasted Letterman responded. “Oh, for heavens sake!”
