The One With the Cast of Night Court
S3 E3:
Free-spirited, "Fatal Attraction"-like stalker Claire Harper (guest star Jennifer Aniston) randomly shows up in New York to visit Liz (Tina Fey) and Jenna (Jane Krakowski). Claire zeroes in on Jack (Alec Baldwin) upon first sight and claims him for her own. Kenneth (Jack McBrayer), distressed and let down over the new page uniforms, turns to Tracy (Tracy Morgan) for some cheering up. To make Kenneth smile again, Tracy has a surprise involving the cast of "Night Court." Also stars Judah Friedlander and Katrina Bowden.
