Tina Fey is an incredible woman and every time she has something new and more surprising for all of us in store. When Dave Letterman was leaving The Late show, she decided to give him a memorable departure gift and so while she was live on the television, she asked Letterman to unzip her dress. That sounds a bit weird, but Dave was more than happy to do the honors considering he is a man. And when he did, people saw Tina in her spandex with Bye Dave written on them. We are sure Dave was happy with the gift, but the audience must have been shocked for a moment!
