Tina Fey joined the ranks of Drew Barrymore when she stripped off her dress in front of retiring talk show host David Letterman on Thursday night. Why did she do it? Because she rules. And also for another hilarious reason.

The "30 Rock" icon said she's done dressing up for talk shows since Dave was the cream of the crop, and she only wore ladylike sheaths out of respect for him. Naturally Fey took of her dress right then and there. And what was underneath? Spanx and a message that said, "Bye, Dave!" It was inspirational. I wish my undergarments had supportive phrases on them.
