Frasier S10 E13 Lilith Needs a Favor

"I'm listening."

Lilith comes to Seattle, and tells Frasier that she would like to have another child. She wants him to father the child through artificial insemination so that Frederick could have a full-sibling. Frasier is hesitant to go along with this, so Lilith tries to manipulate him by bringing up touching stories from Frederick's childhood.
