Summary[]
As Janet is on her way home from babysitting, she stops and tells Ralph that she wants to redecorate her bedroom as a surprise for Chrissy. She has placed an ad for an art student to help and left Ralph's number. She's going to cancel out of a planned ski weekend with Jack and Chrissy. When she gets upstairs, the trio gets into a discussion of how her friend became pregnant by advertising for a partner; she didn't want to get married, just have a baby. In the morning, when she cancels and men begin to arrive at the apartment answering her ad, Jack and Chrissy think she wants a baby also. Chrissy finally explodes at the one Janet chooses to help her, so Janet explains everything. Jack is relieved since Janet declined his offer to help her.
