"Past Imperfect," is part one of a two-part episode. Dan's father, Ed (Ned Beatty), isn't keeping up with his alimony payments. Meanwhile, Jackie doesn't appreciate Fred's (Michael O'Keefe) attitude about her sexual history. Incidentally, the waiter is played by Bob Nickman, a regular writer for Roseanne who would go on to write for Freaks and Geeks and The Drew Carey Show. ~ Andrea LeVasseur, Rovi
