Contrary to the beliefs of obsessive '30 Rock' fans, Tina Fey doesn't have as much of an aversion to exercise as her Liz Lemon character. In fact, she used to work at a gym.

If you happened to find yourself at the YMCA in Evanston, IL during the early '90s, you might have been greeted by the iconic funny girl.

After moving to the area to study improv, Fey revealed in her book 'Bossypants' that she worked for the local Y folding towels and manning the front desk. This should teach you to treat all the attendants at your gym with respect. One day they might become famous enough to spoof you on TV.
