Fey looked off camera before laughing, "I have right? Roll the tape!"

In fact, she felt so confident that she's joined the ladies, she continued, "I think I've been on. I've been on. I'm willing to bet $100 that I've been on the show, so let's roll that clip."

"I'm sorry!" she continued. "My bad, Tina Fey. I'm a senior citizen now, OK? And we tend to forget things, a lot of things, most things. Now let's ask her to come back so we can talk some more." LOL!
