Kelly thinks that Al doesn't respect her as an adult (on account of him throwing her boyfriends out when they try to go up to her room), so she moves into an apartment. Peggy subsequently smothers Bud with affection, treating him like a child, and declares to Al that she wants another baby (he says he would rather dive off the Sears Tower head first onto a thumb tack). Al is worried about his little girl, so he pays her a visit and discovers that she is sharing with a room-mate.
Not an especially memorable episode, but it has its moments: Bud calling a kinky hotline for naughty young men, Marcy paying a visit with her new boyfriend, and Al bashing Kelly's boyfriend Jake into the bannisters, wall and door before launching him out of the house (some great physical comedy from Ric Waugh, who is now a Hollywood producer and director).
