Liz tries to get everyone on the TGS staff to be on their best behaviour when an adoption agent stops by to observe whether she is fit to be a mother.

Liz's former roommate comes to visit (guest star Jennifer Aniston) and takes an immediate interest in Jack.

Jack introduces Liz to his eccentric friend Gavin Volure (Steve Martin), while Tracy worries that his children are plotting to kill him.

Don Geiss wakes up from his coma and has a surprise for Jack, whose attempt to help Liz attend her high school reunion goes horribly wrong.

While Liz decides to do charity work over the holiday period, Jack finds himself searching for a way to avoid going home to his mother.

Jenna thinks Liz is only attracted to a guy because she wants a child, while Jack helps Tracy and his wife Angie develop a `post-nup', and helps get Jenna an audition to play Janis Joplin.
